Hi,

I have aprox 25 Citrix PS 4.5 Rollup6 Servers, all running on Windows Server 2003 SP2, virtually on XenServer. All servers same farm.

4 of the Citrix Servers are experiencing slow logons, both ica and rdp sessions. When loggin in using a admin user there is no problem.

All 4 server are originally a clone.


Any ideas?

Rgds,
Hanne

Are you using roaming profiles? Check copy data from the console of the problem servers to your roaming profile location (i.e. the fileserver on the network), compare speed with a server that's not got the issue. Are the profiles roaming correctly to the problem servers?
You can enable userenv logging: http://support.microsoft.com/kb/221833
Look for delays in the timestamps of the entries in the log file.
Of course you've check the System & Application event logs?

Robincm nailed it on the head: check the application and system event logs and turn on userenv logging.  Good job robincm :)

Hi,

Yes we are using roaming profiles. The location is not different than for the other server. I have already turned on  userenv logging, but cannot see anything "wrong", compared to a logon from another server.

The only event in Event viewer is: Windows has detected that Offline Caching is enabled on the Roaming Profile share - to avoid potential profile corruption, Offline Caching must be disabled on shares where roaming user profiles are stored.

I have to mention again that all these servers are a clone. I have run XenApp Cloning Tool.

Have you turned off Offline Caching on the roaming profile share?

I'd still like to know what network transfer rate you're getting from these servers to the roaming profile network store. If it's loads less than the other servers that's your problem.
We need to be able to rule out network connectivity issues (or not!).

Hi again,

I have now testet filecopy between different servers. It loads the same. I also turned off Offline caching on the Roaming profile share. I removed antivirus for testing purpouse, but no luck in that either.

When a user loggs in, the loginbox with "Running Logon Scrips".... hangs several minutes. But I can open programs while box is still there.... And again, when I login with a user who has admin rights it logs on fine.

So I tried to remove the logonscript from the user. No change. Deleted profile.

What version of XenServer?  Did you disable all the Offload Checksum stuff?

Hi,

I would try to give the domain users group full control to HKLM\SOFTWARE\Microsoft\MSLicensing on the thin client/ Or the PC they useing ....  

http://forums.citrix.com/thread.jspa?threadID=237201&tstart=45



Then the next step if that didn't work would delete the License000x key on the Xenapp server

The users can successfully log on to other servers on the same net, in the same farm. These servers are a clone of one of the other servers.
