Windows

i am finding it a little complicated can anyone please help me.

I have installed SPYBOT on the server windows 2003 where it takes the all the updates and it then should also distribute to the clients.

First Part:
It does take all updates from the spybot and store on the server,but the point where i get confused is how do i distribute this to the rest of the clients.

Second Part:
Configuring the Spybot,when i configured spybot it actually stores everything on the update.reg file.

Third Part:
I thought of using the Active Directory for software distribution but very unfortunately it only takes .msi files.

Can anyone please help
