NW 6.0.5 server.

Rebooted the server after GroupWise WEBAccess caused a soft abend. Suddenly
NetStorage started prompting for a login when you select upload or
download. The login fails and redisplays the login screen. No error
messages are displayed, just a new login page.

We haven't changed anything on the server and I have looked at TID 10070833.
Interesting thing is NetDrive works.
