Assign Computers Update Profile Based on Group Membership

[RCD_Matt 0]

I'm currently stuck with a v5 remote admin console (it has to support endpoint 4 for a win 2000 server) and I'm trying to find a way of assigning  update policies based on a parametric group.

I've created the group and this is populated with the correct clients and I have created and saved the update policy under the Windows Desktop v5 folder of the configuration editor but I can;t find a way of applying the policy to the group automatically.

The end result that I am trying to achieve is to have all laptops (all clients whose hostname matches *LT*) get an update profile that points it directly to the ESET servers whilst everything else points to the local ESET admin server.

Am i going about this the correct way? Is this actually possible in v5?

Thanks Matt
