Recent customer onsite job I had to setup Exchange rollup 3 for the Exchange servers with fingers cross to fix some of the existing issues. Environment consists of 2 HUB/CAS in NLB mode and 2 MBX servers in DAG.
Previously I’ve already applied rollup 2 for all servers. During the rollup 3 setup to one of the HUB/CAS servers I’ve been thrown with an error of “The user who’s currently logged on doesn’t have sufficient permissions to install this package. You need at least Exchange Server Administrator permissions on the current computer to complete the task.”
Since I’ve used the same user account for the pervious machine rollup 3 update I know there is no permission issues for the account. To isolate the issue I tried running the update with logging enable by using the following command,
Exchange2010-KB2529939-v3-x64-en.msp /lxv* c:\Rollupdat3.log
Error log didn’t help much with the given details apart from pointing out ,” Exchange ADAccess service not being able to access AD” This can be easily fix by restarting the “Microsoft Exchange Active Directory Topology” service. No luck when ran the rollup.
Did some research on the net to see if I’m the only guy with this pain J According to the internet search I did, one of the fix that did work for me is,
1. Stop the Exchange services, IIS Admin, WWW, Windows Search (Exchange) and WMI service.
2. Restart the server and trying the setup again.
