Michael, Make sure you are running the latest version. I have no problems running under 5.0.37. I had connection problems before upgrading so it is worth a shot. Here is the article for direct connection that I used. http://www.isaserver.org/tutorials/Configuring_Web_Proxy_Clients_for_Direct_Access.html Is that how you configured your setup?

With the proxy enabled, I still get the "Peer's certificate has an invalid signature" error. It just occurs after a connection to the proxy server is made. The entry in the web proxy ISA log says that it made the connection; however, it returns a 64 error code (The specified network name is no longer available).
