RE: [ActiveDir] Upgrading Hardware for Windows 2003 DC

[Frank Abagnale]

Hi Neil, Brian, Fred,

 

Thanks for your responses, having searched on the message groups, I have come across a few people who have suggested than renaming a Windows 2003 using the Netdom function is not a good idea without backing it up with a viable reason.

 

Neil - what was the reason you decided to go with the renaming route? why didn't you go down the route that Brian & Fred suggested e.g demote the DC and re-promote the new hardware with same IP/Name.

 

Thanks

 

Frank

One potential gotcha is that if your DCs register SRV records in their own local copy of the zone and not on some other remote DC/DNS server, then when a DC is demoted the SRV records will only be removed locally and will still appear on the remote copies of the zone.

 

Solution: ensure that the DC to be demoted deregisters records on a remote DC/DNS server.

 

As an aside, I have performed a similar upgrade path (to your own) and performed the following steps:

1. Promote DCa with IP 1

2. Demote DCb with IP 2

3. Change DCa to use IP 2 as per http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/Operations/80e432f2-10b6-4768-8a3e-54e357e8fc44.mspx

4. Rename DCa to DCb as per http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/Operations/2ffc842c-6841-40e0-b903-fb3838f6ac26.mspx

 

HTH,

Subject: [ActiveDir] Upgrading Hardware for Windows 2003 DC

 

Hi,

 

I am planning on replacing my existing Domain Controller hardware with new HP Servers. All DC's in my environment are GC's running Windows 2003 in a single Domain Forest.

 

The area I am unsure about is that I've been asked to keep the names of the servers exactly the same

 

To keep the names the same and perform an upgrade, do I still need to do a metadata cleanup / remove entries from DNS once I demote the 'to-be-replaced-DC' from the domain, even though I plan to install the same named DC/IP on new hardware?

 

Also, if I have DNS & DHCP running on the individual DC's, are there any gotcha's which you've experienced when replacing existing Windows 2003 Servers with new hardware using the same name & IP address? (I realise DHCP is not recommended on a DC though we're happy to take that risk)

 

thanks...

 

Frank
