Hello, I have two XenApp 6.5 servers, one has had the XenTools upgraded to the latest version after installing hotfix XS62ESP1006 through XS62ESP1021 and updated drivers from 009 on XenServer 6.2. The XenApp server that has had the tools upgraded is showing close to 30 XenDPriv.exe processes running with about 20 users logged into the server. The server that has not had the tools upgraded is showing only one XenDPriv.exe process running with about 15 users logged into the server.

 

Has anyone seen this before?

 

Thanks

We are seeing the same issue.  The issue started after upgrading xentools with the version that was included with XS62ESP1020. Everytime a user logs in another XenDPriv.exe process starts.  The process never closes when the user logs off.  We opened a case with Citrix.  Temporarily we have disabled the Citrix Xen Guest Agent service and killed the processes.

There seems to be some major issues with this release of the XenTools. We have had 4 different servers blue screen when trying to upgrade to this version along with the XenDPriv.exe issue on the XenApp 6.5 servers. We have stopped upgrading the XenTools on clients for now until Citrix puts out a fix/new version because we don't trust the tools with XS62ESP1020.

We are seeing this aswell on XenServer 6.2 with all the hotfixes installed.

There was a specific hotfix for XS 6.5 SP1 regarding Xentools: http://support.citrix.com/article/CTX142583 .

After installing it, the XenTool installation issues for Windows went away for us.

Niklas,

Well, just because it isn't on the HCL doesn't mean that it won't work -- only that it's not been verified. IMO, it would be worth trying to see if it does work.

Hi Tobias,

 

Yes I know, but if I run into problems after upgrading with something else the conversation will look like this:

 

1) Me: Im having trouble with XYZ, running XenServer 6.5 SP1 with all hotfixes.

2) You: Have you tried rebooting your servers, updated the firmware and made sure you have ALL the latest hotfixes?

3) Me: Yes I have tried everything, I even re-installed from scratch and still im having trouble with XYZ.

4) You: Are your servers on the HCL?

5) Me: No they're not, remember the XenDPriv.exe-problem I had on my ~120 VMs?

6) You: Well, go away, your hardware isnt on the HCL so its your problem!
 

And I'll cry a little bit before reverting back to 6.2 where I had the XenTools-problem ;-)

Try this at your own risk(Which did work for me!!)

 

Check the following registry key and make a note of Logoffchecksysmodules key, which is typically "Xendpriv.exe" 

HKLM\System\CurrentControlSet\Control\Citrix\wfshell\TWI

 

Go to folder when Xentools is installed, typically c:\Program files(x86)\Citrix\Xentools and note the file name for XendPriv.exe, if you have uppercase P here and lower case p in Registry, change the file name to xendpriv.exe

 

Reboot and that should fix it!!

 

Logoffchecksysmodules registry value is case sensitive which of course is not mentioned in the article below though

Try this at your own risk(Which did work for me!!), if you can't upgrade soon and need a fix.

I havent tried the above suggestion, but upgrading to XenServer 6.5 SP1 and all the latest hotfixes worked in our case.
