I have one PC, with IIS and NT4 installed. There are two netwerkcards installed, with two different IP-addresses. Each IP-address has a website installed. One networkcard is used to connect to the second. (I don't know how exactly it is named, but it works fine). This is working perfect for over more than 3 years. Since last month, the second website, the one that is reached through the first, isn't accessible, unless I reboot the PC. But after a while, it hangs again.
