I poked a hole in my firewall for 389 in order to access my AD server using LDAP tools however, when I attempt to telnet or connect on that port I get nothing.

What is the name of the service on the AD server that is listening on 389 or do I need to turn one on?  Also what dn would I use if I just want to login as administrator?

Thanks

This would also be a good place to install wireshark or netmon and really see what is going over the wire.  Great way to learn more about AD and the network.

By default, if your domain were domain.local you would use:

CN=Administrator,CN=Users,DC=domain,DC=local

Hmm that was only half your question really, the other guys had helped you with the ports.

Can I re-open this so they can be included?
