Hello all, It's not really a problem as such, just a general question. Has any experienced any issues when applying Server Pack 1 to a domain controller in a cluster? We've got 6 DCs in total and I was unsure if there would be any problems with syncing back with the rest once the server had restarted - mainly to do with being on a different version. I was planning on installing Sp1, one DC at a time from a stand-alone installer. This way seemed easier to manage (compared to doing all 6 at once) and slightly quicker (I don't have to waste time with Windows Update downloading as well as applying). Any thoughts appreciated, anecdotal or otherwise. (Apologies if this question isn't being asked in the right area)

Hi, There is no issues in installing SP1 on Domain Controllers. You can install SP1 one by one on them, there will be no replication issues.Thanks and Regards, Mukesh.

Hello, no problem in installing them. Just assure to have an up to date backup incase something fails, but this should already exist.Best regards Meinolf Weber MVP, MCP, MCTS Microsoft MVP - Directory Services My Blog: http://msmvps.com/blogs/mweber/ Disclaimer: This posting is provided AS IS with no warranties or guarantees and confers no rights.
