Configuring new DSC Pull server - error Nº1 - Error executing Start-DSCConfiguration

Hi all!

I'm starting another series of posts about my experiences with PowerShell DSC!!

As it can not be otherwise, I'm going to start with an here we go!

the error:

You just configured a your new DSC Pull server, using xWebService resource, and created your first MOF file that you are going to use to start DSC Pull server configuration, and run:

Start-DscConfiguration -Path c:\\PullServer -Wait -Verbose

After some information messages...
The expression after '&' in a pipeline element produced an object that was not valid. It must result in a command name, a script block, or a CommandInfo object.
    + CategoryInfo          : InvalidOperation: (:) [], CimException
    + FullyQualifiedErrorId : BadExpression
    + PSComputerName        :

the solution:

This error appears because of known issue #143, reported in GitHub.

Although the version is in dev(at the moment I write this post), you can go here, download the full zip and copy files:\xPSDesiredStateConfiguration-dev\DSCResources\MSFT_xDSCWebService\...

Then you only need to overwrite the old ones (remember to backup) at:
C:\Program Files\WindowsPowerShell\Modules\xPSDesiredStateConfiguration\\DSCResources\MSFT_xDSCWebService
That's all!

Error enabling Operations Manager Audit Collection Service with SCOM 2016 TP4

Hi all,

If you want to install Operations Manager Audit Collection Service and the Audit collection services Collector Setup Wizard finishes with the following error:
start adtserver service: failure 0x00002098
...should it mean that you have some problems with the SPNs(Service Principal Name). If you check the Event Viewer,  you will find the following error registered:
EventID: 7023
Source: Service Control Manager
Message: The Operations Manager Audit Collection Service service terminated with the following error: Insufficient access rights to perform the operation.
Then the solution it's easy, you need to register the required SPN in order the service can start correctly:

Management Server:

  • AdtServer/FQDN DOMAIN\account
  • AdtServer/NetBios DOMAIN\account
  • MSOMHSvc/FQDN DOMAIN\account
  • MSOMHSvc/NetBios DOMAIN\account
Database Server:
  • MSSQLSvc/FQDN:1433 DOMAIN\account
  • MSSQLSvc/FQDN DOMAIN\account
  • MSSQLSvc/NetBios DOMAIN\account
Ok...let's go to see a real case...

Suppose you has a management server named "ScomServer", database server "RandomDBServer" and a domain named "". Then the "Operations Manager Audit Collection Service" is running under "Network Service" account and the "SQL Server" service running under "TheXdom\sqlEngineAcc". Then you need to run in a elevated command prompt:

  1. setspn -S AdtServer/ TheXdom\ScomServer$
  2. setspn -S AdtServer/ScomServer TheXdom\ScomServer$
  3. setspn -S MSOMHSvc/ TheXdom\ScomServer$
  4. setspn -S MSOMHSvc/ScomServer TheXdom\ScomServer$
  5. setspn -S MSSQLSvc/ TheXdom\sqlEngineAcc
  6. setspn -S MSSQLSvc/RandomDBServer TheXdom\sqlEngineAcc
Don't worry if your environment still have one of these SPN, the -S parameter checks it for you!

If these steps cannot solve your problem, perhaps you need to check this Microsoft KB

Hope it helps!

explorer.exe and Print Management suddenly stops in a Citrix environment

Hi all!

Some weeks ago I hit my head with a easy but annoying error: When a user opens a explorer.exe or Print Management published application in a Citrix environment, the application suddenly stops/disappear with no error message. After a time troubleshooting, it seems to appear a hidden error message: Server execution failed

In spite of we have two different errors: explorer.exe and Print Management, the error is the same because Print Management application runs explorer.exe with a parameter.


Citrix 7.5 running Windows Server 2008 R2.

The problem:

The error appears because Windows Explorer looks for "Personal" folder specified in the registry hive:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\

If the folder does not exist, fails.


The problem was detected and solved by Microsoft with the KB2444677

If you cannot apply the KB article(restart needed, or others...) you can do two actions:
  1. Change the folder path for an existing
  2. Create the specified folder

Hope it helps!

Hi all,

Sometimes we do not want to read large articles explaining all the detailed information about an issue, code or anything else. We want it fast and running in not much time.

This is the reason of these new series of articles which always will have this structure:

  • [FastToUse] - Tag in the subject
  • What? - A short summary about the article
  • Fast Instructions - The instructions, if needed
  • Code/Bug/... - The core of the article with "the information"
  • More information - Links with detailed information if you want to explore more.
let's go to write!

Error starting cluster service in a Windows 2008 R2 Cluster

This post born after hours trying to resolve a Cluster issue, and without finding nothing clear in internet!

The problem:
Suddenly the second node of a Windows 2008 R2 Cluster, gets down and there are no way to start it up! The Event Viewer shows the following errors in System log:

Source: Service Control Manager
Event Id:7031
The Cluster Service service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 60000 milliseconds: Restart Service
Source: Microsoft-Windows-FailoverClustering
Event Id:1069
Cluster resource 'Cluster Disk 1' in clustered service or application 'Cluster group' failed.
Source: Microsoft-Windows-FailoverClustering
Event Id:1573
Node 'node_name' failed to form a cluster. This was because the witness was not accessible. Please ensure that the witness resource is online and available.

I tried to restart the server and to stop and start the cluster service with no success.

After that, I checked out the iSCSI configuration in the server and in the SAN, and I found some misconfigurations. After solving it, the problem continues, perhaps this is the origin of the problem, but not all is solved.

My third step is to run cluster service with log using the command:
cluster log /g
You can find the result in %windir%\cluster\reports. I could not see anything useful and went to revise every key of cluster in the regedit configuration at HKLM/Cluster, following some errors found in cluster service log....again no success.

Finally I decide to remove the node from the cluster and rejoin, and SOLVED. Some times its better to start from the end.

To remove a failed node from a cluster:

  1. Run this command from the failed node in elevated Power Shell:
    1. Import-Module FailoverClusters
    2. Clear-clusternode
  2. From the cluster administration MMC > right click on failed server, under nodes > More Actions > Evict
After step 2, you can add the node again into the cluster, and check Event Viewer for additional bugs.

Hope it helps!

Error installing Exchange 2010 SP2 Rollup 5v2

I managed with this error in Windows 2008 R2 and Exchange 2010 SP2...

When you try to install this update you can find one or all the following errors in the EventLog or in the Windows Installer Log:

 Microsoft Exchange Server - Update 'Update Rollup 5-v2 for Exchange Server 2010 Service Pack 2 (KB2785908) 14.2.328.10' could not be installed. Error code 1603. Windows Installer can create logs to help troubleshoot issues with installing software packages
DEBUG: Error 2826: Control BottomLine on dialog FatalError extends beyond the boundaries of the dialog to the right by 5 pixels The installer encountered an unexpected error while installing this package. This may indicate a problem with this package. The error code is 2826. The arguments are: FatalError, BottomLine, to the right
msgErrorExchangeAdmin = The user who's currently logged on doesn't have sufficient permissions to install this package. You need at least Exchange Server Administrator permissions on the current computer to complete this task.

Basically we have two different problems:
  1. We have a compatibility problem with one update
    • The incompatible update is: Windows Management Framework 3.0 , in my case, at the end of the name, appears "(beta)".
    • You should uninstall it and reboot the system, then continue with step 2.
  2. We need to run the installer with admin privileges
    • Run the update from a Command Line window executed as Administrator
That's all for me!

If you are installing this Rollup update because you need to solve problems related with Retention Tags, Calendar and Tasks I recommend to visit THIS blog.
