I have a mixed windows server DC 2003, 2008 servers.
I was on 2000 level forest , before i add 2008 server. and dns was created in 2000 forest level. But i have changed it 2003 forest level and transfer all the FSMO to 2008 server. They all work fine before this happens.
If we get power loss and all the server went down, if you to try to power on 2008 primary DC, it loops around for twenty minutes before it launches and does not work. It does not even see anything on dns and active directory. but the moment the 2003 old server comes online everything works.
I have not depromoted 2003 it still active, but does not have any Fsmo, but still 2008 server which holds all the fsmo, does not work properly without the 2003 domain controller.
I don't understand what to do?
