Disabling Forefront for Exchange 2010 when Installing Exchange Service Packs and Hotfix Rollups

Belatedly installing Microsoft Exchange 2010 Service Pack 2 Hotfix Rollup 2 this week, I once again was niggled by the need to manually disable Forefront for Exchange first.

Unknown to me, the Microsoft Exchange designers included the right hooks into the product to make this easy.

A quick web search led to an Exchange Team blog post from back in June 2010, entitled "Sample script to disable and enable Forefront service during patching".

Unfortunately, their sample script leaves a lot to be desired, and isn't general enough to be useful everywhere.

So I've tweaked it into a more sensible form, which you can download here.

It should be placed in <Exchange installation folder>\Scripts\Customization

On my Exchange 2010 systems, that's C:\Program Files\Microsoft\Exchange Server\V14\Scripts\Customization

Create the Customization directory if it does not already exist.


1: If Forefront for Exchange isn't installed, do nothing.

2: If one of the listed services is not present on the box the script is run on, treat it as successfully started/stopped and continue.

3: Wait until the service is successfully stopped/started, or for 3 minutes, whichever happens first (easily modified to suit your environment and experiences). Based on a code snippet by andreister on StackOverflow.

The end result is that the same copy of the script can be deployed to all Exchange 2010 servers in your organisation, and it just does the right thing.


Postscript, May 30th

There's a bug in the original which rendered the script ineffective. The path to the FSCController executable, retrieved in line 62 of the script, is enclosed in double quotes. These need to be stripped off for the script to do the right thing.


    $imagePath = $imagePath -replace '"(.*)"', '$1'

after line 65 strips the offending " characters. Fixed, properly tested in an Exchange 2010 SP2 RU3 install.
