Re: Win3k Forest Trusts

We are trying to setup a trust between our DMZ and Internal network. The DMZ and Internal network are their own Forest both running Win3k with SP1 (firewall disabled). We have a firewall sitting between the two domains and we opened the necessary ports between them according to this MS link ( We have successfully created a one-way trust between the two forests. We are able to validate the trust without any errors. The problem comes when we are on our DMZ SQL server and try to add a new login with an AD user in the other forest (Internal). Our Internal domain shows up in the drop down menu but when we try to add a user it says the domain is unavailable.
Maybe we have our trust setup incorrectly. Any ideas on what we could look at in our situation.
