I have a big problem with the Novell Client 4.91 SP4 and DFS access.
We have two Windows 2008 Servers and enable DFS.
When I try to access the DFS share with an XP/Win2003 client with installed Novell Client 4.91 SP4 with all Patches or Novell Client 4.91 SP5 with all patches, the access takes a long time. Up to 6 minuits.

When I try to access the DFS Share with the same Client without any Novell Client it works without any problemes. I can access the DFS share in 1 or 2 secounds.

I try some stuff from these TIDs:
TID-10090785 Slow preformance opening explorer or UNC locations or accessing MS servers. ( 29JAN2004)
TID-10093266 How does the Novell Client Bad Name Cache work? ( 20APR2006)
TID-10065560 Poor performance accessing Microsoft Office documents on a Novell server. ( 04NOV2003)

But nothing works.

I read that these problem will be fixed in a Novell Client 4.91 SP 2. But it seams that the fix is not working or is removed in the other clients.

Perhaps someone has an idear what i can do.
