net rpc join failed with 2008 server

[feroz ahmed]

When i run "./net rpc join -U administrator" I'm getting error "Unable to
find a suitable server".

I have logged this bug in bugzilla with bug #5328. Logs and smb.conf
are created
as an attachment in bugzilla.

In fact with 3.0.28a I'm able to join 2003 server by using "./net rpc join
-U administrator" command with out any problem.

Also I'm able to join 3.0.28a to active directory. (./net ads join -U
administrator" is success)

Any help in this regard will be appreciated.
