As Malke posted, you can work around the issue by setting Vista to a lower
security level. You can also upgrade Samba on your MacPro to version 3.0.22
or later and add "client ntlmv2 auth = yes" to your smb.conf -- this may
also help your performance.

Michael,
thanks for you help, too. I will work around your solution asap, I'm still
fresh on MacOS X and I need to gain confidence in using it
