We have a pretty standard Windows network setup here. Windows 2008R2 AD, DNS, etc.
I also have an ISA 2006 server setup in single adapter mode, it has web filtering software installed, that's all it's really used for. It only has 1 nic.
Clients default gateway points to our Cisco router. Browsers have proxy settings pointing to the ISA server, and all works well.
In IE if I uncheck "Use a proxy server..." I am unable to get online. What if our ISA server goes down, or I want to remove it from the network?? Clients will be unable to get online?
Any help would be greatly appreciated, thanks.
