Symptoms:
- DHCP Server is listed with the wrong name
- DHCP server is listed with a red –
- It won’t authorize
- Choose “All Tasks” and all options are grayed out
- You can delete it using the red X on the toolbar but it just comes back when you add your server to DHCP
I feel your pain, everything on the internet tells you how to use NETSH or ADSIedit to fix your problem but your problem is not on a domain controller. What do you do?
Open C:\windows\system32\drivers\etc
Open the hosts file with notepad and remove the entry that has the rogue server name and the current IP address. Click save.
Re-open DHCP console and you should be good to go.
This was experienced on a Windows Server 2008 R2 server that had the Quickbooks 2010 database admin installed. The rogue server name was similar to QB_servername_20
