Additionally, I usually disable the windows networking protocols by unbinding them from the external interface. Generally, if I don't need a service, I disable it.

One word: Firewall. Block all access to those ports from anything outside or your site. I think there may also be some filtering code available, but, since I don't use it, I don't know anything about it. BTW... For those of you playing with Windows 2000, add port 445 to the list of things that should be blocked from outside contact. You can do the same sorts of things with port 445 that you can with port 135. > -K Mike -- Michael H.
