First, make sure your firewall ports are open on the system for your
particular network profile, as Windows 7 has various profiles defined by
location.

Second, add to the registy the key specified in the the following
article:  http://support.microsoft.com/kb/957441

Third, add sec=ntlmv2 onto your mount command as Windows 7 requires this
as default.

I had a similar problem with 2008 servers a while back and changing the
registry key really helped.  I just tested it out on Windows 7
Enterprise and the connection worked after adding it and rebooting.
