We migrated a 2003 server running exchange 2003 to temp server running 2008 std edition with exchange 2010.
the migration completed succesffully and exchange was working on the temp server.
we then formated the orginal server loaded 2008 std and added it to the same domain that the temp server was running on .
we then migrated AD and it went through successfully when trying to install exchange we got the attached error .
