If I were in your shoes... I would go into regedt32 Dig into hklm\system\ccs\services\tcpip\parameters Put in my new dns host name into the NV Domain value. Reboot.
This should straighten it out for you. You will want to verify the DNS entries afterward and also verify the SPN's got updated properly and replication is normal. Unfortunately I have had to do this many times since April 2000 even before MS agreed it was possible as we had a disjoint namespace and decentralized DNS management, we tended to catch when DNS names changed on the fly as our replication monitoring would pick up the phone and say FIX ME! joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thommes, Michael M. Sent: Friday, July 09, 2004 7:38 PM To: Active Directory Mailing List (E-mail) Subject: [ActiveDir] domain suffix rename of DC possible? I have a domain controller that I need to rename (I think). This DC sits in a separate site. Recently, networking redid the forward lookup record in the Unix DNS server for this DC from "spock.dis.anl.gov" to "spock.dc.anl.gov" when they "rebadged" the entire subnet. Now I have a child DC that thinks it is "spock.dis.anl.gov" but DNS says it is "spock.dc.anl.gov". An enterprise dcdiag report says that it cannot contact the DC, spitting out the following: Testing server: ANL-WashDC\SPOCK Starting test: Connectivity * Active Directory LDAP Services Check The host df4e1849-e5ce-407b-b8b7-d31305ce7e7f._msdcs.anl.gov could not be resolved to an IP address. Check the DNS server, DHCP, server name, etc ......................... SPOCK failed test Connectivity We have this record in our AD-integrated DNS: df4e1849-e5ce-407b-b8b7-d31305ce7e7f CNAME spock.dis.anl.gov but there is no longer a "spock.dis.anl.gov" in DNS. We even tried a CNAME chain (alias) entry in the DNS server but that didn't work. Can I, somehow, rename the server while it is a DC or do I need to DCpromo it out, rename it and then DCpromo it back in? Any pitfalls to watch out for? Thanks for any info!
