[Samba] Cannot Access Linux Shares from Domain Client

[Dennis Clark]

If the client (WinXP Pro, SP2) is joined to a domain (Win 2003), the client is denied access to the linux share.  If the the ip address is used rather than the netbios name, access is granted.  If the client is not joined to a domain, access is granted using netbios name, as it should.  All users are affected including admin.  Group policies are in effect for the client but only one gpo is linked, with only a few settings.  Samba is acting as the wins server.

Any ideas?
