Can't Open Network Share After Windows Updates

I have several PCs that received the updates that I pushed out from my WSUS server on Friday.   This morning they appear to be having problems opening or running programs from an absolute path.  ie. :  \\high_school\sys\public\clntrust.exe does not work, but they ARE receiving drive mappings during login and can run programs from a Drive letter.

The clients are running Novell Client 4.91 SP5 attaching to a Netware 6.5 SP7 server.

All users are Administrator on the local machine, the firewall is off.  They have rights to the share.

I had network connectivity issues after applying update KB958644 to an XP laptop last week, and ended up removing it, which magically restored the adapters' (wireless and wired) functionality. I realize those aren't the same symptoms, but you might try uninstalling that one update on one machine and see if it resumes working correctly.
If not, try removing the other updates one-by-one on the same computer and see if that process isolates the problem (possibly none of them are responsible, of course, in which case you could reapply them to that one machine and be back where you started on this problem).

What OS[s] are the Novell clients running on?

I'll see what I can do by removing some of the updates.

The client OS is Windows XP SP3.

Well... I removed all the updates one-by-one that were installed last Friday and the problem/symptoms still exist.

Anymore ideas?

Do you have a restore point on the computer(s) prior to Friday when the updates started?

You could try running "%windir%\network diagnostic\xpnetdiag.exe" on one to see if it finds anything wrong.

Does Novell have a similar tool to check for IPX/SPX problems?

IPX/SPX?  NetWare hasn't needed that since 1998.  NetWare 6.5 SP7 prefers pure IP, and does IP at least as well as Windows if not better, since NetWare supports IETF standards like SLP...

That said, have you tried clearing the UNC path filter cache (bad server name, bad address)?  It's possible the NetWare server got put into the bad server name cache for some reason, which would route the UNC path request to the Windows client.

Also check the provider order.  It's possible that an update did something to screw up provider order.

If the paths are to NetWare volumes as I suspect they are, perhaps the Windows client is trying to be "boss" for the UNC-path type access instead of letting the Novell Client32 rule (as it should, since it can actually play "traffic cop" instead of timing out and making a big lag for anything non-Windows like the Windows client does.)

Side note - you shouldn't have to specify any sort of path to clntrust - SYS:\Public should be your number-1 search mapping in your login script:

map ins s1 = sys:\public

If that's in your login script, just put "clntrust.exe" all by itself - it'll run because of the search mapping (usually "Z:")

Glad to see people are still using BorderManager.  I loved it when I had it.  Now I have to deal with IWSS (not by choice.)

P.S. - NetWare doesn't have "shares" - you're confusing the 'softies by calling the UNC path to a volume\directory a "share" in your Question.  They'll be thinking about all sorts of AD/NTFS stuff that doesn't apply to your situation.

I wound up reimaging the few (out of 100's of PCs) that were giving me this problem and it hasn't cropped up again.
