We have 4 samba servers all running RHEL4u5 samba version 3.0.27a, and one of the 4 servers is not allowing Windows Vista to access its samba shares. When we issue dir \\bb02f79.unx.sas.com\sasgen, it returned "The Parameter is incorrect", and others listed files.

We compared their config file, and everything are the same except netbios name.

Here is the error log:

Thank you for helping, as our vista users are dead in the water.
