Please file a bug report with Microsoft for this issue.  The problem
is not with OpenAFS but with the Netbios Name Resolution.  If you

 nbtstat -n

you will see that the "AFS" <20> Netbios name has been successfully
registered on the Microsoft Loopback adapter (10.254.254.253) and yet
when you attempt to access \\AFS, (net view \\afs), Windows reports
that the name cannot be resolved.

This is a bug in Microsoft Windows 7 and Server 2008 R2.  Until
Microsoft receives enough reports from paying support customers,
it will not be fixed.

When you file your report, please indicate that Microsoft when
investigating the problem can contact openafs-gatekeepers@openafs.org
if they want to discuss the issue privately with the OpenAFS project.

Thank you and I am sorry your users are experiencing this problem.
