I need to "migrate' my entire network to a new IP subnet. This includes a Windows Server 2003 R2 running AD and Exchange 2010 running on Windows Server 2008 R2. This is the only Exchange server on the network and it is running all 3 roles. I don't know if it makes a difference but I have a SonicWall NSA 2400 that is running anti-spam for this server. Here is what I tried:
1. Dismounted the Exchange databases and set them to start manually.
2. Set all Exchange Services to start manually (but did not stop them).
3. Shut down the junk store on the Exchange server.
4. Created a new AD site on the 2003 R2 AD server.
5. Activated DHCP scope.
6. Changed the IP address on the 2003 R2 AD server and moved it to the new site.
7. Flushed & registered the DNS cache on the AD server. (it did show in DNS with the new IP)
8. Rebooted AD server just to be sure
9. Changed the IP address on the Exchange server.
10. Flushed & registered the DNS cache on the Exchange server and waited for it to show in DNS.
11. Rebooted the Exchange server.
12. Checked connectivity between AD server and Exchange server (ping, etc.) and everything worked fine.
13. Manually started the Exchange services, starting with MS Exchange Active Directory Topology (it took a while but it did start)
14. Tried starting the other services manually and of the 18 that needed starting, 10 failed to start.
MS Exchange Address Book-error 1067
MS Exchange EdgeSync-error 1053
MS Exchange Information Store-error 2415
MS Exchange Mail Submission-error 1053
MS Exchange Protected Service Host-error 1053
MS Exchange Replication-error 1053
MS Exchange Service Host-error 1053
MS Exchange System Attendant-error 1053
MS Exchange Throttling-error 1053
MS Exchange Transport-error 1053
I know that the 1053 errors are essentially a timeout error but I'm not sure what was causing the timeout. I couldn't find any direct correlation between service dependencies. Since the services would not start, I did not attempt to mount the databases.
I was able to retreat back to the previous IP/site settings and the Exchange server did recover after about 15 minutes. When I retreated back, the services would not start right away, but after starting the Topology service and then waiting, everything started back up (Happy Dance!)
I have been told by a contractor that an IP migration is possible with Exchange 2010, so now I need to know what I'm doing wrong (or missing) because I'd rather do this in house.
Thanks in advance for your help!
