I had exchange 2003 sp2 installed on DC w2k sp4 server in windows 2000 domain.
while upgrading the domain to w2k3 R2 on new hardware
I left the exchange server on the same hardware
but I demote the w2k server to a member server (now I realize that it was a mistake)
now I got fully functional w2k3 R2 domain with exchange 2k3 sp2 on w2k sp4 member server
for a while evrything looks fine
and I wanted to move the exchane to a new w2k3 r2 server using the move mailbox wizard
after installing another exchange server on new w2k3 r2 server.
the problem is - when I move mailbox to the the new server it stop receiving mail
i found :
"After you install Exchange Server 2003 on a server, do not change the role of the server"
like I mentioned it was a mistake.
how can I fix this situation ?
I think about reinstalling the exchange on the server but I'm not sure what happened to the data and configuration
if reinstall is the solution , should I first uninstalling the second exchange server (just one test mailbox on it)
another possibility is move the exchange to anew hardware by using the Setup /disasterrecovery
explained in http://www.microsoft.com/technet/prodtechnol/exchange/guides/SvrConsUsingE2k3/f2762572-f001-42e6-adc3-84a2a847f303.mspx?mfr=true
but I split it to anoter question
thank for any profesional help
