I have about 40 computers hitting the proxy during the day. For the most part the proxy server keeps going down. No errors it just freezes and I have to hard boot it to bring it back up. Does anyone have anything that may help. When internal attpemt to pull up our website they can not. It works outside but not inside. This is the error we get on the Webpage. "HTTP 502 Proxy Error - Internet Control Message Protocol (ICMP) network is unreachable. For more information about this event, see ISA Server Help. (10051) Internet Security and Acceleration Server" If they refresh their Browser screen they get the site to come up. When they go to a new page it fails on their computer again. After a few minutes it causes the server to crash. After a fresh reboot it is all fine but then again I have to go through the whole process again. This is a new network to me so I am not sure. Is there a Max/Min clients allowed setting on the ISA. Also is there a time limit a connection is allowed that could be causing this? I checked to make sure there where no "energy management" settings that where on. So I am not sure why I have to continue to reboot the machine so that people can reconnect to the Proxy. This only effects all internal computers. Our external site is fine. Thanks For the Help All... James J. Capone
