Recompile the complete WMI repositories and then run the following commands for recreating these files.

Recompile Microsoft Windows .MOF files:

net stop winmgmtc: cd %systemroot%\system32\wbem rd /S /Q repository
regsvr32 /s %systemroot%\system32\scecli.dll regsvr32 /s %systemroot%\system32\userenv.dll
mofcomp cimwin32.mof mofcomp cimwin32.mfl mofcomp rsop.mof mofcomp rsop.mfl for /f %s in ('dir /b /s *.dll') do regsvr32 /s %s for /f %s in ('dir /b *.mof') do mofcomp %s for /f %s in ('dir /b *.mfl') do mofcomp %s 

Recompile Citrix .MOF files:

cd %programfiles%\citrix\system32\citrix\wmi for /f %s in ('dir /b *.mof *.mfl') do mofcomp %snet start winmgmt

We have seen a rash of these problems on Windows Server 2003. Research seems to indicate the problem is related to the installation of Windows Server 2003 Service Pack 2 (SP2).
The simplest fix we have found is this:

• Open a Command Prompt
• Run the following commands
  • %SystemDrive%
  • CD %windir%\PCHealth\HelpCtr\Binaries
  • start /w helpsvc /svchost netsvcs /regserver /install

The service should install and start automatically.

The Citrix XML Service service on Local computer started and then stopped

CITRIX XML SERVICE :

If you ever do any research on what port to use for the XML service in a Citrix XenApp environment, you’ll notice that there are options to share port 80 with IIS, use port 443 with SSL on IIS and finally port 8080.  I haven’t really found any official documentation on what is best practice but I was able to find forum posts where Citrix engineers recommend the use of port 8080 and not to rely on IIS.

The process of changing the XML service port to 8080 is quite easy but since I know I’m bound to forget after not having to perform the configuration on a regular basis, I thought it would be good to write a blog post so I can reference it in the future.

Begin by logging onto your XenApp server and stop the Citrix XML Service:

Once the service has been stopped, proceed with opening up the command prompt as an administrator an executing the following command to unregister the Citrix XML Service port:

ctxxmlss /u

Once the command completes successfully, proceed with executing the following command to register the port to 8080:

ctxxmlss /r8080

Once the command successfully completes, proceed with starting the Citrix XML Service:

… then open up the registry to confirm that the changes have been applied via the following registry key:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\CtxHttp

Name: TcpPort
Type: REG_DWORD
Data: 0x00001f90 (8080)

Once the port change has been confirmed, log onto your Web Interface server and reconfigure the farm settings for your websites:

Troubleshooting ICA Client / PNAgent Error 2306

Program Neighbourhood Agent / PNAgent Error 2306

On setting up the ICA Client 10.105 I received the following error on trying to connect via the applications listed under the PNAgent.', 'On setting up the ICA Client 10.105 I received the following error on trying to connect via the applications listed under the PNAgent:

This was being caused because the ICA file was being deleted before the PNAgent had finished reading it… very strange. After browsing a few forum posts I found that by modifying my local workstation registry I could resolve the issue by changing the ‘RemoveICAFile’ entry to equal false:

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Client Engine\ICA File

Alternately, if you are an Administrator wanting to resolve this for all of your PNAgent users and Web Interface users simply follow these instructions:

Modify the \Inetpub\wwwroot\Citrix\MetaFrame\conf\default.ica on all of your Citrix Servers that have the web interface.

Change the line "RemoveICAFile=yes" to "RemoveICAFile=no"
