Windows 7

I thought it was the same for Vista and 7 : set the client to allow the use
of NTLM v1. By default Vista and 7 use NTLM v2 and do not fallback to v1 -
even though that is one of the available options. So much for MS and Novell
working together to ensure interoperability of their products (I hold MS
accountable in this case).

If that isn't it then I don't know what it is....

Cheers,
