Slow on logoff.

[Erik]

When a user is connected to the wired lan, then disconnects and connects to a
wireless hotspot and tries to log off or shut down the normal 14 seconds
ballon up into the minutes.

I've narrowed the process down to GPClient, but as to what exactly GPClient
is trying to do that is causing the increased time I have not figured out.
Any suggestions on drilling down more on GPClient?

Logoff scripts have already been ruled out of the equation as a source of
problems.

Made no difference.

It seems that "netsh interface tcp set global autotuninglevel=disable"
would fix the problem.
