I have 2 servers (1 email server and a reg. file server) in the DMZ of a PIX520, 1 NT and 1 2000. I did a AD/2000 migration of our domain controller from NT, and now the servers in the DMZ cannot authenicate to the DC. I put in all the conduit statements needed by 2000 but it still doesnt work. All machines on the inside work fine. Also, i can ping across to all the machines and also resolve domain names using ping -a etc, cleared arp cache and Xlate as well. When the DC was a NT machine everything worked. Any help is appreciated.
