If authentication was
successful:

is specified in the domain name
(such as
domainname.xxx.com), make
sure that DNS is specified in
"Interface Settings".
2. If a NetBIOS domain name
is specified in domain name
(such as DOMAINNAME),
make sure that WINS is
specified in "Interface Settings".
Authentication is unsuccessful:
1. Make sure that Restrict LM/
NTLM is not set in either
"Domain Controller Security
Policy" or "Domain Security
Policy".
Authentication is rejected
because NTLMv2 is not
supported.
2. Make sure that the ports for
the domain control firewall and
the firewall on the machine to
the domain control connection
path are open.
