All of a sudden (we've not made any changes recently) random people are not able to connect to random servers.

when they login, they'll get an access is denied and then none of their login scripts will map

When I check their Novell Connections, I see a "not authenticated" to the server it original denies them access to.

Further, we have some ZEN NAL apps that are running stuff from a UNC path and random people are getting 1612 errors, and when I check, that server shows up in the Novell Connections as "not authenticated" either.

The servers are NW 6.5.7, 6.5.8 and OES2 SP1 Linux, so there's no rhyme or reason as to why it's doing this or why it started happening all of a sudden.

Any ideas?
