Thanks all. I wasn't aware of the GPMC issues - to clarify - you just have to run GPMC on a 32 bit server, right? (so we can still run it on our existing admin terminal server as we do now). -Brian

No WS08 DCs installed yet, but we just extended our schema for WS08 over the winter break and that went well-still ticking along. We've also had to keep a 32-bit DC for GPMC, but I'm hoping when we get to WS08 I can get rid of that. BTW, just to clarify, AFAIK, there is no direct upgrade path at the server level-the DCs I installed as x64 had to be rebuilt. -Bonnie From: Tim Vander Kooi [mailto:[email protected]] Sent: Wednesday, January 07, 2009 7:44 AM To: NT System Admin Issues Subject: RE: Upgrading DCs to 64 bit I have been running a mix of 32 and 64-bit DCs for over a year with no ill effects at all. I prefer the performance gains I receive from running 64-bit, but not all MS management tools (GPMC in particular) would run on 64-bit prior to Server 2008's release, so I had to keep at least 1 32-bit server around for that purpose.

Our security team wants to move to 64 bit to take advantage of the larger event logs - anyone done it? Were there any issues running some DCs 32 bit and some 64 bit? Anyone run a mixed environment long term? I'm planning on doing some testing, but wanted some advance scouting if available.
