For Enterprise array deployments is the correct order of installation on the EMS first and then the proxy array members next?
It looks like this rollup requires you to install it via a command prompt opened with elevated privileges. If you attempt to execute this rollup via the Start/Run method you will likely receive the infamous, “Setup cannot modify or create the registry entry System\CurrentControlSet\Services\Tcpip\Parameters” error. The installation will then bomb-out.
No reboot is required after installing this patch either on the EMS or the proxy itself.
Yes. EMS first, then the reporting server for the array and the rest of the array members after that. There’s even a script on ISAtools.org that will tell you specifically which server to run the update on. More details here:
Correct. The update requires administrative privileges to run, so running it from an elevated command prompt is required.

This could be caused by any number of things, really. Unfortunately I don’t have the time to thoroughly help you troubleshoot your issue. I’d suggest posting your question on the forums at ISAserver.org. You’ll get much better response there. 🙂
