You would be much better off to use a sort of name resolution (ie WINS or
LMHOSTS depending on your environment) instead of opening up ports on your
routers. I have done this thousands of times and it works flawlessly. If
you need more information, I can post it later.
Opening those ports can be dangerous. It can also be detrimental to your
WAN performance.

Be careful with those ports. They are easily exploitable in the MS
environment.

Subject: RE: Microsoft Networking over WAN
TCP 137
UDP 138
TCP 139 would be required for ms networking
you may also need ip helper-address and ip forward protocol udp if you are
doing DHCP across the wan.

Could someone please give me the required ports that need to be open so
I can map drives, and login to a NT Server? Also is there anything else
I should know about doing Microsoft Networking over a Cisco Router WAN
connection?
Thanks.
