Hello,
is there a log off scan in progress? Or another something prosess in log off?

Best Regards.

Do you see any ccapp.exe related error at log off?

You can try to disable Tamper Protection and Check,

try to log in to the Console with the local administrator.

1. Logg of Windows
2. Log in locally with the local administrator

Check if this solves the issue. If the problem is solved, then the issue is related to the credentials you have installed the SEPM with.
In this case, repair the management with that local account.

We do not see a ccapp.exe error
 

same issue logged in with local administrator

is it everytime you logg off or its some time???
Do you have backup exec software on the client??

In SAV there was a similar issue caused because of Tamper Protection and Profile Sync during Log off

How was the logon process?  Did you install sep with firewall?

Disable the Application and Device Control and check if this solves the issue.
Please tell us the result.

Did disabling the App&Dev Control work? I am seeing a similar issue where by SEP with DEV/App Ctrl causes LONG delays in logoffs (Win XP SP3) but when the service is off (agent and SEP prot services) it does NOT occur? It seems that SEP is "Slowing" up a logout process we have whereby "robocopy" copies info automaticvally for the user on logout...
