Problem Deploying Clients

I have installed BPP5 on our SBS2003 server and I have attempted to deploy it to a few test clients. On the clients (Win XP Pro) it removed Avast 4.x, installed the new client, rebooted - and that was it.

I checked on the client and the firewall was enabled - I have set the group to disable the firewall, so it looks like it isn’t pushing out my config with the client installer. Also the clients are reporting they are in ‘trial mode’ and not licensed, though the server recognises the licence (20 user).

Is the fact the firewall is enabled then stopping the console from connecting to the client, or is there another issue?

Thanks

Seems somehow similar to my issue:

Got to be some kind of bug surely?
