THIS IS DRIVING ME OVER THE EDGE! My outlook 2k client will not resolve the name from the address list on my exchange 2k server. Outlook express works and so does OWA. This is a test enviroment with only 3 people mailbox including me. I have run through 4 days of testing and can't figure this out. All the obviuos has been checked eg. nslookup, ping, DNS and WINS. Any suggestions would be great I will try them Thanks Armando
