Here's what I have.
1 SBS 2008 box, and 1 2008 Standard box. The SBS box is the DC, and I am wanting to setup a proxy server to help with our downloads of updates and such so that it can be cached on the proxy serer and save on bandwidth. We had done it previously with a 2003 SBS inside ISA but with 2008 having ISA removed, I am a little lost on this one. Both servers have Dual nics and are both Dell Poweredge 2900's. I would prefer to use tools and software solutions that are no or low cost.
