I installed sp5 to our 6.5sp3 netware server then added the post update
nw65sp5upd1 and since then users are having sporadic login problems.

The tree information is there but they are receiving messages like
cannot login you in.

Anyone familiar with this, any known fixes out there.

It seems that if I either re-install the client or add a service pack to
it, it will then log the person in, restarting the computer isn't enough.

Any ideas anyone?
