Here is my network setup: Exchange 5.5 Server running on a Windows 2000 Server Domain Controller. The DC is also running AD, DNS, DHCP and WINS. I've successfully introduced an exchange 2003 running on a windows 2003 server into my exchange 5.5 organization. I am trying to move user mailboxes over to the new exchange 2003 server using the move wizard in exchange, but unable to. The event viewer is giving me the following errors:
Event ID: 9175 - THE MAPI call "Open store" failed with the following error: the information store could not be opened. The logon to the microsoft exchange server computer failed ID no: 80040111-0286-00000000
Event ID: 9167 - Unable to get an administrative interface to the mailbox store on server DDS-Design error: The information store could not be opened The logon to the microsoft exchange server computer failed
Event ID: 1008
Event ID: 8197
Event ID: 1005 - 0xc1050000 - network problems preventing connection to the ms exchange server computer. M<API was unable to load the information service emsabp.dll be sure the service is correctly installed and configured. MS exchange address book id no: 00040380-0000-00000000 occured
I'm not sure if this is also part of the problem that I cannot move mailboxes but, Outlook is still pointing to the old Exchange 5.5
I have also read that installing Exchange to a DC, running all that is running in my DC and AD is not a good IDEA, I am wondering if I need to promote my Windows 2003 server eunning exchange to a Domain Controller or upgrade my 2000 DC to 2003.
