I have inherited a client with a new situation than I have faced before and all the research I've done has made no progress so I come to you guys for advice so I can learn what I do not know.
The DC is named "COMPANYNAMESERVER" ... When I opened the DHCP console it shows a server with a different name than that of this server. It says something like "WIN-Z8X67" or whatever. The server has a big red stop sign icon over it and you cannot click on it or expand it for more information. If you delete the server it disappears then if you go to add an authorized server and enter my own IP address or "COMPANYNAMESERVER" it takes you to the next window and shows Server Name as "WIN-Z8X67" again!
So somewhere in here it thinks this server is named "WIN-Z8X67" - but I went into ADSI Container, Services, Net Services, checked DHCP root and it does not show this old computer name.... I have checked DNS for old entries.... I don't know what to do to add this DC as an authorized DHCP server can anyone guide me how to troubleshoot this? Did I provide enough details to make the problem clear?
