First, I strongly recommend that you update the Samba server to version
3.0.2a. Reasons are: Security (2.2.1 is very old and has issues),
Compatibility with Windows Server 2003.

Second, Are you running WINS on your Samba PDC? Is your Windows Server
2003 configured with the IP Address of your WINS server in it's TCP/IP

You will need to identify how your Windows server is resolving the name to
the IP address it is arriving at. The best tool you can use to debug this
is ethereal. See http://www.ethereal.com.

You might also refer to chapter 10 of the Samba-HOWTO-Collection.pdf (see:
http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf - also
available from Amazon.Com as the book "The Official Samba-3 HOWTO and
Reference Guide").

For the rest we can speculate about your problem, but that may not help
