Hi Rob, I believe you should be able to do this with nothing more than DNS (this is how Windows clients do it). Once you have the DNS domain of the machine you're on (_SERVER["USERDNSDOMAIN"]), query for SRV records called the following: Name: _ldap._tcp.dc._msdcs.<machine domain name> That should return one or more records in the answer, each one will be the FQDN of a domain controller.

I know as an administrator I can use dsquery and various other administrator commands, but I'm unsure how to do so within PHP from an unprivileged vantage point.
