I have about 4 websites hosted in IIS 7.5 on different ports, when I try pulling them up on my local network (using WAN IP) sometimes they load very fast, and sometimes the websites completely freeze and don't process my requests (I get the "The server at IP address is taking too long to respond" error.) After a few minutes I'll try the url's again and they work again.
Is this a configuration issue in IIS? or in the operating system (windows 7 ultimate 64 bit), or maybe an issue in the router or my ISP(TWC)? Should I try reinstalling IIS?
