I have inherited a single server AD domain network. This server obviously holds all roles including DNS and DHCP. The issue is the server name only shows as "server", there is no dns suffix appended to it. The domain seems to functioning correctly except for the dns error obviously for the domain controller.
I have read through Microsoft KB888048 and in checking the DOMAIN registry value it is indeed blank. I need to add a new 2008 R2 SP 1 DC to this enviroment. That of course entails updating the AD. My question is I could not decern if the fix in the article, which seems simple enough, can be ran on the PDC without causing a critical issue to the enviroment. Also, if I were to update the AD to support the 2008 R2 DC, if this could be a possible fix or because of the issue fail or cause a more serious issue to the enviroment.
Thank you in advance
