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!

  • What? - A short summary about the article
  • Fast Instructions - The instructions, if needed
  • Code/Bug/... - The core of the article with "the information"

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.

Biztalk cofiguration error Nº 1

After tens of BizTalk installations I decided to post a collection of errors found.

The first one it's an easy one!

The error:

While you are in the BizTalk configuration wizard, with BAM configuration, you get this error:

ERROR: Failed to set up BAM database(s).
There was a failure while executing nscontrol.exe. Error:"Microsoft Notification Services Control Utility

The Solution:
You need to solve the problem in 2 steps:

  1. Install SP2 of SQL 2005 Notification Services
  2. Copy the DLL to the GAC
    1. Open a CMD console with administrator privileges and run:
C:\Windows\assembly\GAC_MSIL>copy Microsoft.SqlServer.Instapi\ c:\Microsoft.SqlServer.Instapi\\Microsoft.SqlServer.InstApi.dll 

C:\gacutil.exe /i Microsoft.SqlServer.InstApi.dll
