DHCP Server MMC Console showing wrong DomainName (2K8 R2)

Experts,

I've stumbled upon another strange error.  After promoting a server to a DC (2K8 R2), everything went as smooth as could be expected, until it came time to install the DHCP role onto the unit.

In my environment, I have a SBS domain that has an alternate UPN suffix.

On the server that I just stood up as a DC in this network, AD replication and everything checks fine.  The DHCP console on the other hand, has the alternate UPN suffix listed, instead of the regular domain name.

When I attempt to "add server" to be able to manage it from that same console, I'm given a list of both my authorized DHCP servers (the one with the bad console too), but when I select the server name and add it to the console, nothing actually happens.  The console still just has the alternate UPN name listed.

Clicking on the alternate UPN name just gives a red-background circle with a white line through the middle icon (like a "do not enter" sign)

I can however, manage the DHCP server completely by connecting to it from a remote console with absolutely no problems.

Would anybody happen to know what that's all about?

Hi,

Make sure when you add the DHCP to mmc make sure you do it under a Domain Admin account.

Also, try running a ipconfig /flushdns

Thanks for the ideas.  Unfortunately, these didn't change the outcome.

- But now, even with the wrong domain (Alternate Principal Name) the MMC at least is functional now.  I'm guessing it was able to replicate something in the background about authorized DHCP servers - so I no longer get an error.

It shows the wrong domain name, but it's managable.  I guess we take what we can get.  :)
