We have a 2008 server, hosting 40 domains. All of our projects are developed in asp.net and using iis 7.5 in our server. Nearly 35 of these domains are sharing one IP and the other 5 is sharing another Ip. Everything was fine till 4 days ago. Then one of our Ips (shared with 35 domain) began to serve very slowy. Wep pages are hangs while loading. The interesting thing is the other web pages sharing the other IP are fine, they are loading in a normal speed.
we checked the logs of http.sys, but found nothing different. We checked iis logs and find nothing.
Can anyone tell us the ways or steps to follow to find the problem ?
thanks in advance
