NLAsvc timeouts in XenApp 6? Users can’t log in? users can’t log out? CryptSvc service timeouts?
“The winlogon notification subscriber <Sens> is taking long time to handle the notification event (Logoff)” messages?
Take a look at this hotfix http://support.citrix.com/article/CTX129741
contains many fixes in one package. However, applying this hotfix alone will not sort out the hanging issues.
You should also follow this step:
7. A session can be terminated before the first application launches. The issue can occur when a one-minute time-out is exceeded, for example, when the profile share is located across a WAN link rather than on a local share.
This fix introduces support for the following registry key that allows you to configure the time-out as follows:
Data: <desired additional time-out, in milliseconds>
Note: Specifying a value of less than 10000 reverts to 10000 because 10 seconds is the minimum override.
In this case, I was instructed to increase the value up to 300000 by support, and have not had any further hanging issues in xenapp 6/remote desktop since. Hurrah!
