Yesterday I attempted to replace our only server (domain controller, GC, DNS, etc) with a new server we purchased. The old server is running Small Business Edition 2003 and the new server is Standard Edition 2003.
After making new server a domain controller, Installing DNS, assigning it global catalog and transferring FSMO roles successfully. I noticed on reboot, it took very long at preparing network connections and when finally logged in, I noticed Error in event log saying
"Active Directory could not resolve the following DNS host name of the source domain controller to an IP Address, this prevents additions, deletions, and changes in AD........"
When I try and demote old server from being a DC, it says it can't find any other DC's on domain and cannot continue.
PLEASE HELP, VERY URGENT
