I recently restored a domain controller, the only server in a small network, due to hard disk failure. I installed the new hard drive and reinstalled Win2k Server along with updates and SP4. Before promoting the new server to a domain controller, I restarted and entered AD mode and restored a backup of the system state and sysvol folder. After restarting, I noticed a lot of errors in event viewer concerning DNS and DHCP. Also, the icons for AD Computers and Users, DHCP and DNS were missing. The services were installed and functioning just the icons was missing. To get the icons back, I had to install full admin tools. Why is this so? Should I have promoted the new server to a DC and then restore the system state backup?
