fizban2 Posted January 13, 2008 Share Posted January 13, 2008 IF you are using Windows 2003 DC's, the concept of Primary and Secondary Domain Controllers no longer applies. All DCs hold the SYSVOL and all pertaining information that is required to service clients. you can either use add/remove programs to add the DC role, or using DCpromo from the command line. this also will help in the fact that your Domain will be more better equiped to handle loads and also will provide redundency if Either domain controller goes down. Hope that helps! Link to comment Share on other sites More sharing options...
cluberti Posted January 13, 2008 Share Posted January 13, 2008 The only caveat is that if you truly want them to be mirrors of each other, you need to make sure they both hold the global catalog. Link to comment Share on other sites More sharing options...

cluberti Posted February 18, 2008 Share Posted February 18, 2008 ...And the same I like to make with exchange server 2003 alsoI forgot to touch on this in my previous post - you will need a cluster (2 servers, external storage, either SAN or (i)SCSI) to achieve this kind of thing with an Exchange server.

cluberti Posted February 18, 2008 Share Posted February 18, 2008 You can use NAS now - sort of: http://support.microsoft.com/kb/888374I've tried it. Definitely not something I would suggest for a prime-time Exchange cluster, it's just not robust enough. It worked fine with one Exchange instance on an active/passive with about 200 users, but when we bumped it up to 4 instances on an active/active/passive/passive setup with about 1000 users, it crumbled under the I/O load. Went back to fiber, no problems. Even SCSI kept up pretty well (we tried it just for kicks to see if it would scale, and that was pushing the limits of the technology), although it had it's moments of faltering under heavy load.
