Weve just put a new server onto a site and linked it up over VPN. The main site is running an SBS server with exchange etc and the second site is running server2003 with exchange. Weve yet to perform the transition (using packs anyone know whats its like?) on the sbs server to make it server standard so we can do dcpromo etc. The second sites server is running as a member server and has exchange as part of the same global group. We have migrated some mailboxes from the old serverto the new server and that worked fine. The problem is that although external mail works for both servers and the old server can email people on the new server for some reason the people on the new server cant email those on the old server. Things ive done:
Ive checked dns is working correctly
ive checked the advanced button in virtual servers and that field is empty
ive checked telnet but for some reason the old server cant telnet to the new server although it cant telnet to anyone but then machines on the domain can telnet to the new server (im thinking antivirus is stopping this)
ive logged in over telnet and sent a test email and that doesnt work
Basically all the emails are being queued up and not being delivered. help!
