Hi Ingo,

Hope all is well.

I've experienced this as well. I found the following document:


(search for Enabling and Requiring MAC Signing)

to be quite helpful.

AFAIK WK2003 requires MAC signing by default. In our environment we
disabled this (set RequireSecuritySignature to 0) so that it behaved
like the other W2K/NT machines.

Not sure if this is a possibility in your environment, but it's
something you can test to find out if MAC signing is what's preventing
your access from working.

Hope this helps.
