Windows 2008 Scheduled tasks result codes

To trouble shoot your scripts started by the task scheduler, and trying to figure out why it doesn't work:

  • 0 or 0x0: The operation completed successfully.
  • 1 or 0x1: Incorrect function called or unknown function called.
  • 2 or 0x2: File not found.
  • 10 or 0xa: The environment is incorrect.
  • 0x41300: Task is ready to run at its next scheduled time.
  • 0x41301: Task is currently running.
  • 0x41302: Task is disabled.
  • 0x41303: Task has not yet run.
  • 0x41304: There are no more runs scheduled for this task.
  • 0x41306: Task is terminated.
  • 0x8004130F: Credentials became corrupted HOTFIX available
  • 0x8004131F: An instance of this task is already running.
  • 0x800704DD: The service is not available (is 'Run only when an user is logged on' checked?)
  • 0xC000013A: The application terminated as a result of a CTRL+C.
  • 0xC06D007E: Unknown software exception.

    Check OWA page with login and report when fails

    After the millionth time the helpdesk come complaining that OWA wasn't working, I made this script that checks the status of the OWA webpage by logging in and reporting back if the login attempt fails.

    The script:

    A few things are necessary;
    login.txt:      the user that logs in to OWA needs to have a mailbox and the password file needs to be generated every time the password is renewed.


    # Check if Outlook Webapp is online
    #
    # Use the 3 lines below to generate an encrypted password file for the user that will be logging into the site for this script
    # $MyPswd = "password"
    # ConvertTo-SecureString $MyPswd -AsPlainText -Force | `
    # ConvertFrom-SecureString | Out-File -FilePath "D:\Scripts\Login.txt"


    $username = "domain\username"  # user needs a mailbox
    $password = Get-Content "D:\Scripts\Login.txt" | ConvertTo-SecureString
    $cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $password
    $logfile = "D:\Scripts\WebPageLoginResult.txt"

    if (Test-Path($logfile))
     {
      remove-item $logfile
     }

    Test-OWAConnectivity -url https://webmail.domain.com/owa -MailboxCredential:(Get-credential $cred) | fl url,scenario,result | out-file $logfile
    Test-OWAConnectivity -url https://webmail.domain.lan/owa -trustanysslcertificate -MailboxCredential:(Get-credential $cred) | fl url,scenario,result | out-file -append $logfile
      
    $Body = Get-Content $logfile

    Get-Content $logfile | where {$_ -match "skipped"} | foreach {Send-MailMessage -SmtpServer smtp.domain.lan -From OWA_Check@domain.com -To username@domain.com,username2@domain.com -Subject "Webmail is not working" -Body ( $Body | out-string )}
    Get-Content $logfile | where {$_ -match "failed"} | foreach {Send-MailMessage -SmtpServer smtp.domain.lan -From OWA_Check@domain.com -To username@domain.com,username2@domain.com -Subject "Webmail is not working" -Body ( $Body | out-string )}

    Remove activesync devices not synced for 60 days or more

    For Exchange 2010:


    Get all devices not synced for 60days or more:

    $DevicesToRemove = Get-ActiveSyncDevice -result unlimited | Get-ActiveSyncDeviceStatistics | where {$_.LastSuccessSync -le (Get-Date).AddDays("-60")}

    Delete active sync devices from variable:

    $DevicesToRemove | foreach-object {Remove-ActiveSyncDevice ([string]$_.Guid) -confirm:$false}

    Remove Active sync device for specific user:

    Get-ActiveSyncDevice -Mailbox "domain\username" | Remove-ActiveSyncDevice -Confirm:$true 


    And for Exchange 2013:


    Get all devices not synced for 60days or more:

    $DevicesToRemove = Get-MobileDevice -ResultSize unlimited | Get-MobileDeviceStatistics | where {$_.LastSuccessSync -le (Get-Date).AddDays("-60")}

    Delete active sync devices from variable:

    $DevicesToRemove | foreach-object {Remove-MobileDevice ([string]$_.Guid) -confirm:$false} 

    Remove Active sync device for specific user:

    Get-Mobile -Mailbox "domain\username" | Remove-MobileDevice -Confirm:$true

    Outlook web access opens in "Light mode" by default on Windows 8.1

    If you upgraded to Windows 8.1 and tried to access Outlook Web App with the new Internet Explorer 11, you probably noticed that the “Use the light version of Outlook Web App” checkbox is checked and disabled on the login page:

    owa-light

    That means that IE11 is willing to render only the basic version of OWA which was originally designed to target legacy browsers. This is quite embarassing, because IE11 is a really modern browser even in the preview!
    The solution is to force IE to render OWA in compatibility mode. You can add the site to the compatibility list in the Tools –> Compatibility View Settings dialog:

    compatibility-view-settings

    This didn’t solve my problem, because only top-level domains can be added to this list, but I could take the advantage of the fact that according to the first checkbox, intranet sites are by default rendered in compatibility view. So I added my OWA URL to the list of sites in the Intranet Zone in the Tools –> Internet Options –> Security –> Local intranet –> Sites –> Advanced dialog.
    According to some forum posts, the same issue arises with Office 365 and some popular websites like GitHub as well.

    This attachment was removed

    After applying a file extension filter in Forefront Protection for Exchange 2010 we got complaints about .PDF, LNK, and .ZIP files not getting through.

    The attachment would be removed and replace by a text file with the line "This attachment was removed" in it.

    The first thing that attracts attention is the line "This attachment was removed".
    This is not the standard text we configured in Forefront so it comes from another source.

    Turns out after a standard install of Exchange 2010 (Edge) server, under water there is also a file filter active: "Attachment Filtering agent"

    You can see this after running:

    As shown above, the attachments .ZIP, .LNK, and .PDF are not shown.
    Problem is that the attachment gets identified as an "invalid attachment" by the "Attachment Filtering agent".

    Solutions;

    Disable-TransportAgent -Identity "Attachment Filtering agent"

    Restart-Service MSExchangeTransport

    Or:

    1.Stop the Microsoft Exchange Transport service.

    2.Locate the EdgeTransport.exe.config file. This file is located in the following path:
    drive:\Program Files\Microsoft\Exchange Server\Bin\
     
    3.Add the following entry between the <appSettings> element and the </appSettings>  element          of  the EdgeTransport.exe.config file:
      
    <add key="AllowInvalidAttachment" value="true" />
    4.Restart the Microsoft Exchange Transport service.

    Automatically enable users in a particular OU for Lync 2010

    I was trying to get Forefront Identity Management to provision a new user and enable Lync for this user through provisioning code.
    Turns out this is a not supported feature, and can only be done through codeless provisioning.

    A way to to do this is by running a script on the lync server (frontend).
    This script searches for all users in a specific OU and checks if the value "enabled" is set to true.
    If not (blank) then according to the email address the users gets enabled for lync and set to the correct pool.

    The script:

    import-module 'C:\Program Files\Common Files\Microsoft Lync Server 2010\Modules\Lync\Lync.psd1'
    get-csaduser -filter {Enabled -ne $True} -OU "ou=Employees,dc=domain,dc=lan" | Enable-CsUser -RegistrarPool lyncpool.domain.lan -SipAddressType EmailAddress

    How to Install Updates on Exchange Server 2010 Database Availability Groups

    This one is a must read for every Exchange admin, thanks to Paul Cunningham who posted this excellent topic on how to and why you should use the DAG maintenance scripts provided by Microsoft.

    How to Install Updates on Exchange Server 2010 Database Availability Groups

      
    An Exchange Server 2010 Database Availability Group (DAG) provides several benefits to an organization, primarily that of continuous availability of mailbox databases.
    To update the DAG members with new patches, update rollups or service packs, the update process should be managed to prevent all of the DAG members from being offline at the same time.
    To do this you can move the active mailbox databases off a particular server so that it can be patched, and if necessary rebooted, without causing any downtime for mailbox users on that database.
    This tutorial demonstrates how to update the servers in an Exchange Server 2010 Database Availability Group without causing downtime. Because this process differs depending on the version of Exchange Server 2010 you’re running I’ve covered each method here.
    • Preparing an Exchange Server 2010 RTM DAG member for updates, or
    • Preparing an Exchange Server 2010 SP1 DAG member for updates
    • Stopping Conflicting Services
    • Disabling Server Monitoring
    • Updating the Server
    • Verifying the Update
    • Returning an Exchange Server 2010 RTM DAG member to production, or
    • Returning an Exchange Server 2010 SP1 DAG member to production
    For this tutorial Update Rollup 4 for Exchange Server 2010 is being installed.

    Preparing an Exchange Server 2010 RTM DAG Member for Updates

    The first step is to move active mailbox databases to another DAG member so that the server can be updated.
    To see a list of mailbox databases and their current active server use the Get-MailboxDatabase cmdlet.

    [PS] C:\>Get-MailboxDatabase
    
    Name                           Server          Recovery        ReplicationType
    ----                           ------          --------        ---------------
    Mailbox Database 02            EX1             False           Remote
    Mailbox Database 01            EX2             False           Remote

    In this example I want to apply updates to server EX1, and I can see that it currently hosts the active copy of Mailbox Database 02.
    If your environment has a lot of DAG members and mailbox databases you can refine this query to only show active mailbox databases for a specific server.
     
    [PS] C:\>Get-MailboxDatabase | where {$_.Server -eq "EX1"}
    
    Name                           Server          Recovery        ReplicationType
    ----                           ------          --------        ---------------
    Mailbox Database 02            EX1             False           Remote

    Move the mailbox databases using the Move-ActiveMailboxDatabase cmdlet.
     
    [PS] C:\>Move-ActiveMailboxDatabase "Mailbox Database 02" -ActivateOnServer EX2
    
    Confirm
    Are you sure you want to perform this action?
    Moving mailbox database "Mailbox Database 02" from server "ex1.exchangeserverpro.local" to server
    "EX2.exchangeserverpro.local".
    [Y] Yes  [A] Yes to All  [N] No  [L] No to All  [?] Help (default is "Y"): y
    
    Identity        ActiveServerAtS ActiveServerAtE Status     NumberOfLogsLost   RecoveryPoint MountStatus MountStatus
                    tart            nd                                            Objective     AtMoveStart AtMoveEnd
    --------        --------------- --------------- ------     ----------------   ------------- ----------- -----------
    Mailbox Data... ex1             ex2             Succeeded  0                  14/09/2010... Mounted     Mounted

    All of the mailbox databases are now active on server EX2.
     
    [PS] C:\>Get-MailboxDatabase
    
    Name                           Server          Recovery        ReplicationType
    ----                           ------          --------        ---------------
    Mailbox Database 02            EX2             False           Remote
    Mailbox Database 01            EX2             False           Remote

    As another example, if there were multiple databases active on a server you can move all of them with a single command.
     
    [PS] C:\>Get-MailboxDatabase | where {$_.Server -eq "EX1"} | Move-ActiveMailboxDatabase -ActivateOnServer EX2 -Confirm:$false
    
    Identity        ActiveServerAtS ActiveServerAtE Status     NumberOfLogsLost   RecoveryPoint MountStatus MountStatus
                    tart            nd                                            Objective     AtMoveStart AtMoveEnd
    --------        --------------- --------------- ------     ----------------   ------------- ----------- -----------
    Mailbox Data... ex1             ex2             Succeeded  0                  14/09/2010... Mounted     Mounted
    Mailbox Data... ex1             ex2             Succeeded  0                  14/09/2010... Mounted     Mountede

    Note the use of -Confirm:$false to avoid having to confirm each move. Use this option with caution.
    After moving all active mailbox databases off the server that you are planning to update, the final preparation step is to block activation on the server to prevent it from automatically reactiving a database copy while you are performing maintenance.
    First check the current activation policy on the server using Get-MailboxServer.
     
    [PS] C:\>Get-MailboxServer EX1 | fl Name,DatabaseCopyAutoActivationPolicy
    
    Name                             : EX1
    DatabaseCopyAutoActivationPolicy : Unrestricted
    Next, use Set-MailboxServer to block activation.
    [PS] C:\>Set-MailboxServer EX1 -DatabaseCopyAutoActivationPolicy Blocked

    Preparing an Exchange Server 2010 SP1 DAG Member for Updates

    For Exchange 2010 with Service Pack 1 the process is a little easier thanks to some scripts provided by Microsoft. Open the Exchange Management Shell and navigate to the scripts folder on the Exchange server.
     
    cd $exscripts

    Next run the StartDagServerMaintenance.ps1 PowerShell script.
     
    .\StartDagServerMaintenance.ps1 -serverName ho-ex2010-mb1

    The script will automatically do the following tasks for you:
    • Calls Suspend-MailboxDatabaseCopy on the database copies.
    • Pauses the node in Failover Clustering so that it can not become the Primary Active Manager.
    • Suspends database activation on each mailbox database.
    • Sets the DatabaseCopyAutoActivationPolicy to Blocked on the server.
    • Moves databases and cluster group off of the designated server.

    Stopping Conflicting Services

    If the mailbox server is running any Exchange-integrated services, such as antivirus software, these should be disabled prior to the update.
    For example to disable Forefront use the FSUtility command.
     
    C:\> fsutility /disable

    Another example is Data Protection Manager 2010, which may be configured to perform Copy backups from passive database copies at frequent intervals through the day. Make sure these jobs are paused to prevent errors or conflicts from occuring.

    Disabling Server Monitoring

    If the DAG members are monitored using SCOM or a similar system then this should also be disabled or placed into maintenance mode.
    This will prevent alarms from being raised as well as prevent any automatic remediation actions from being run by the monitoring agent that may cause the server updates to fail.

    Updating the Server

    Install the update following the deployment notes for that update type.
    Update rollups come in the form of a .MSP file (Windows Installer Patch) that is applied to the server. Simply double-click the file or launch it from a command line window.
    Service packs are a complete reissue of the Exchange Server setup files and are installed by running setup in upgrade mode, which can be run in either graphical or command line mode.
     
    C:\> setup /m:upgrade

    Both update rollups and service packs can take some time to install, so plan a large window of time for these updates.


    Verifying the Update

    After the update has completed, and if necessary the server rebooted, you should check the server’s health before placing it back into production in the CAS array.
    Event Logs – look for error or warning events that have started since the update was applied.
    Setup Logs – service packs write a complete setup log file to C:\ExchangeSetupLogs
    Services – check the Exchange services are running (or at least those that you expect to be running, some such as IMAP and POP will be stopped if you have not explicitly enabled them)
     
    [PS] C:\>Get-Service *exchange*
    
    Status   Name               DisplayName

    Returning an Exchange Server 2010 RTM DAG Member to Production

    If the update was successful and the server healthy then it can be placed back into production.
    Re-enable services such as Forefront Protection for Exchange.

    Re-enable monitoring agents and alarms for the server.
    Set the server’s activation policy back to its original setting.
     
    [PS] C:\>Set-MailboxServer EX1 -DatabaseCopyAutoActivationPolicy Unrestricted

    At this stage you might move all of the active mailbox databases to the server that was just updated so that you can update the other servers in the DAG. After all of the DAG members have been updated it is likely that mailbox databases will be active on servers that are not their first activation preference.
    For Exchange Server 2010 RTM you can view the activation preferences for each database, and manually move active mailbox databases to their preferred server.
     
    [PS] C:\>Get-MailboxDatabase | fl name,activationpreference
    
    Name                 : Mailbox Database 02
    ActivationPreference : {[EX2, 1], [EX1, 2]}
    
    Name                 : Mailbox Database 01
    ActivationPreference : {[EX1, 1], [EX2, 2]}
    [PS] C:\>Move-ActiveMailboxDatabase "Mailbox Database 01" -ActivateOnServer EX1

    Are you sure you want to perform this action?
    Moving mailbox database "Mailbox Database 01" from server "EX2.exchangeserverpro.local" to server
    "ex1.exchangeserverpro.local".

    Returning an Exchange Server 2010 SP1 DAG Member to Production

    Once again Exchange 2010 with Service Pack 1 makes this task easier thanks to a script provided by Microsoft. Open the Exchange Management Shell and navigate to the scripts folder on the Exchange server.
     
    cd $exscripts

    Next run the StopDagServerMaintenance.ps1 PowerShell script.
     
    .\StopDagServerMaintenance.ps1 -serverName ho-ex2010-mb1

    The script will automatically reverse each of the actions made by StartDagServerMaintenance.ps1 except that it will not move active mailbox databases back to the server.
    To move the active mailbox databases you can continue to go to each mailbox server in the DAG and run StartDagServerMaintenance.ps1 and perform your updates. When all of the servers have been updated you can rebalance the DAG automatically using a script from Microsoft which is demonstrated here.

    Adding multiple Remote IP Addresses to existing Receive Connectors

    I had to add a lot of ip addresses to our receive connector, but not overwrite the existing ip addresses in the receive connector.
    For that I came across this excellent Powershell script that does just that:
    <#
    .DESCRIPTION
       Simple Powershell script that can bulk import remote IP ranges from a text file in a determined Exchange Receive Connector.
       The Import of the Remote IP ranges maintains the original values which are already present on the Selected Connector.
    .PARAMETERS
       None - execute directly from the Exchange Management Shell
    .Version
     0.1

    Export Receive connector RemoteIpRanges

    Backing up your Receive connector RemoteIpRanges seem like a good idea, to me at least.
    We currently have several hundred ip addresses added to our relay connector.

    Losing all that work by some(ones) mistake would take a lot of work to recreate.

    So here's how to do it:

    First set your output higher, otherwise more than 16 ip addresses added to your connector will be truncated in the powershell output.
    [PS] C:\>Get-ReceiveConnector "Relay Connector" | fl remoteipranges
    
    
    RemoteIPRanges : {10.0.0.14, 10.0.0.20, 10.0.0.19, 10.0.0.18, 10.0.0.17, 10.0.0
                     .16, 10.0.0.15, 10.0.0.10, 10.0.0.9, 10.0.0.8, 10.0.0.7, 10.0.
                     0.6, 10.0.0.5, 10.0.0.4, 10.0.0.13, 10.0.0.12...}
    
    As you can see the ...} at the end of the output means there's more than Powershell shows.

    To unlimit the output for your current Powershell session:
    $FormatEnumerationLimit =-1

    Now we can list all the output to a file:
    [PS] C:\>Get-ReceiveConnector "sr-XXXXX\smtp relay" | fl remoteipranges
     | out-file "d:\temp\smtp relay sr-XXXX.txt"
    This file can be edited to your needs.
