old DHCP server still shows up
Posted on 2008-10-10
I decommissioned an old server over a year ago (Server Name: SRV01)
I built a NEW server (Windows 2003 Server) and made it a domain controller, added DNS, WINS and DHCP.
Upon launching the DHCP console (which is empty by default), I right-clicked 'DHCP' and selected 'Add Server'
When the 'Add Server' dialog box appears there are two sections. The top section allows you to add (or browse) for a DHCP server. The bottom section allows you to select from a list of 'detected' DHCP servers. In that list I see my OLD server! (srv01.domain.com)
Is the DHCP console telling me that it still 'sees' SRV01 on my network, or is it reading that from a registry key, or (most likely) does my entire Active Directory network think SRV01 is still around, and just down for the time being?
I dont want to start having network slowdowns because Active Directory still thinks SRV01 is around somewhere.
Any ideas? I'm not experiencing any issues yet (that I know of), I have 2 domain controllers, all servers are Windows 2003 Server ... just makes me nervouse that SRV01 is showing up in this list.
(By the way I know for 100% certain that there are no devices on my network called SRV01, there are no machines with that name when I browse the network or scan active directory. There's no leftover record in DNS called SRV01 and if I ping SRV01 I get no reply ... I'm not going crazy ;-)
