Deploying(Pushing) avast from ADNM to clients

I have installed ADNM to a server with server 2003 OS. Problem is i cant manage to push the anti virus to clients. it only prompted " request
timed out" every time i run the deployment.

the clients are not running any firewalls?

As above, have you properly set up firewall exceptions?

If all else fails you could probably deploy via SMS if you use it…
