RE: [ActiveDir] IP Address Change

No, they are in 7 different sites. One site has 2 DCs.   The plan I am thinking of now is this:   Network group will change Site’s IP/Subnet. We Change the site and services IP/Subnet info. Change the IP on the Domain Controller. Restart the DC, double check that everything replicates ok and DNS Is consistent   AS for the final 2 in the same site, my idea is to shut one down (transfer the FSMO roles obviously, before changing ip). Change addressing on the remaining one, restart it and check to make sure DNS is consistent. The bring the second one up, change the IP and restart.   Basically change only 1 DC at t a time and always wait for replication/DNS for become consistent before touching the next DC.     Does this make sense or am I missing something?     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rutherford, Robert Sent: Tuesday, July 20, 2004 10:22 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] IP Address Change   1st thing... are they all on one site? -----Original Message----- From: Alex Etin [mailto:[EMAIL PROTECTED] Sent: 20 July 2004 14:56 To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] IP Address Change Hello Everyone!   Our company has just acquired another division, and they already have AD infrastructure in place. Currently they have about 8 Domain Controllers worldwide. Because theirs and our IP addresses overlap, they will be changing their entire IP address infrastructure. Can anyone recommend a best practice regarding changing the IP addresses on all of these domain controllers? Is there a particular order? I am especially concerned with _msdcs.gc folder, because when I tried this in the lab with just 4 DCs everything broke after IPs have changed, and no matter what I did afterwards, the .gc folder would fail to appear. (I tried just about everything, even completely wiping the DNS zone and recreating it, followed by restarting netlogon, etc). Every DC in the lab was set as GC, and I tried setting it on and off, restarting the DC afterwards. Still no .gc folder in DNS.   Thank you very much everyone!   -Alex   This e-mail and the information it contains are confidential and may be privileged.
