Running Trend Officescan in Provisioned Clients

Sometimes there is software that just won’t work “out of the box” on a provisioned image when in shared image mode. Trend OfficeScan Antivirus client is one such beast. Here’s a solution.

The problem arises because when the client registers with the management server, it uses a unique GUID. Now, if all our provisioned images contain the same unique GUID, your management server is not going to be able to differentiate between any of your provisioned clients, and you’ll be in a mess when it comes to reporting on infections or virus definition updates. This is only a problem when you are running your clients in shared image mode as any personalisation is lost between reboots. You can’t “sysprep” the server at each bootup otherwise you end up with lots of duplicate clients in the management console due to a new GUID being created at every boot.

So, Trend needs a little bit of tweaking to work correctly inside a provisioned image. Using a startup script, in combination with the Trend “imgsetup.exe” sysprep tool, (KB article here) you can ensure each provisioned client obtains a unique GUID, and then retains this across reboots.

Attached is a vbscript that allows Trend to operate correctly. The script uses a local cache disc to store the unique GUID, but theres no reason why you couldnt modify this to store the GUIDs centrally on a share, and read them from there if you didn’t have a local cache disc available. The imgsetup utility is part of the OfficeScan installation, although note if you’re using 64-bit provisioned clients you need to request the 64-bit version from Trend support (see this KB article)

You should configure the script to run at server startup (either in a local or group policy startup script)

Im summary the script checks whether the GUID file is present on permanent cache disc.
If so:
– Writes the GUID it into the registry
– Starts the Trend services
If not:
– Runs the Trend “sysprep” tool “ImgSetup.exe”
– Sets the Trend services to manual startup
– Reads the GUID created and writes in to the permanent cache disc

This has the effect that a client will maintain its GUID across reboots, and the correct values will be in the registry when the Trend services start.
