Since the beginning of march it could take a half hour before
a client can login. This problem can occur on any client.
My environment is Netware 5.1 SP8 and Novell client 4.91 with SP1.

I captured some of the communication between client and server with
Etherreal.
I see a lot of messages about NCP en TCP regarding the client which cannot
login.

The NCP messages talks about obtaining info for the client, enumerate
extended
attributes and open or create with Op-Lock

The TCP messages talks about TCP segment of a reassembled PDU
and acknowledgements of tcp segments.

Using SP2 for the client does not help to solve this problem.
