BLGTS1 is our citrix terminal server
Does anyone know why this is happening? The Ctx_cpsvuser does reside as a local account on the terminal server. Everything in TS seems to be working ok. Any ideas to clean this up would be appreciated....

    This will rebuild the account and assign the correct permission.

    Do exactly what dborger suggests or change the ctx_cpsvuser account to "local system".  That is what the account used to be but Citrix wisely changed it for security reasons.  Only change the account if the article dborger suggests does not work.

    sounds good, I am waiting until my next after hours downtime to attempt this. I just don't want to break anything in Citrix!

    I will be attempting this soon, just had some other major work to do and did not want to do this as well. Is there any risk of "breaking" citrix if I do this? Or is the risk pretty low?

    There is ultra low risk.

    The problem mysteriously went away- no more event logs for this citrix user account. I will award points and document the fix in case it comes back.
