I am a new network administrator for a company. I met a interesting issue. One of my servers named "hqfax-new" was a domain controller and i demoted it to a member server recently. But when i tried to input name "hqfax", i still can log onto this server through remote console. When i logon "hqfax" and "hqfax-new", i checked the ip address, i found that they two have the same IP addresss, 192.168.1.11. It made me confused because i am sure there is no server named "hqfax" in my domain.
I guess maybe my new fax server "hqfax-new" is derived from old server "hqfax", my predecessor(the former network administrator) just changed the name from "hqfax' to "hqfax-new" and promoted it to a DC. BTW, after i demoted "hqfax-new", i still see it listed on my DC list under dsa.msc console. I tried to deleted it, but failed. It says "The object HQFAX (or some fo the objects it contains) cannot be deleted because: Access is denied.
Are there any experts here could help me with it? Thank you very much.
