yesterday we suddenly received a few calls from some of our clients (with win7 + nc 2 sp2 ir2) that they receive error
and do not get their drives.

Serverside is sles10sp4+oes2sp3

the only thing that changed on the serverside the day before was that we patched the servers with this new ncp patch (don't remember what the name exactly was).

Looking at the novell clients we saw that under name providers only SLP was selected. But the standard configuration we use is SLP and NCP.
We selected NCP, restarted and everything worked fine.

Now we are trying to figure out how the NCP option could be unset. Definitely no admin has done that.
Any ideas on that?
