I know, the native connect is priority no.1.
But I restarted the system and still get the error msg with no delay. So
I assumed a problem on the fileserver side. I did a bos restart -all on
every fileserver we have and problem was gone.
But a user of us has a "backup script" with some xcopy in it to copy
some local data into AFS space and that script nearly always hung in
between with the network path not found. I have a look at it to get
debug information if time=B4s available.

That would be great. I see what I can do here in the next few days to
get a user setup and login for you.
