Windows Server 2008 R2 DHCP problem "The parameter is incorrect"

A few weeks ago I was decommissioning a domain controller which had the DHCP server role installed. When I tried to unauthorize the server I received the following error:

"The parameter is incorrect"

• I verified that the server was authorized in Active Directory
• I verified that I had sufficient rights to unauthorize the server

These are the steps that solved the problem:

1. Stop DHCP service
2. Delete the DHCP server object from the DHCP console
3. Re-add the DHCP server to the DHCP console
4. Start the DHCP service
5. Try again to unauthorize the DHCP server
