IIS 5.1 localhost very slowly responses when connected to Network
Posted on 2008-10-06
I've got a new Thinkpad laptop downgraded to XP pro SP2 that I do development work on. It's running IIS 5.1 and SQL Server 2005. Whenever it's connected to any network (either via ethernet, wireless, etc) IIS chugs and responses are VERY slow (20-40 secs for the localhost). However, when I'm not connected to a network, the webserver is extremely fast. There are a couple computers on this network, all with similar setups, and they all work fine. I've checked my IP info with the router's DNS settings and the other computers, and it all matches. If I do an ipconfig /release and /renew then things work great for a few seconds but then the server starts the slow responses once Windows acquires the network info. A /flushdns only helps momentarily, but then the problem kicks in again once the network info is acquired. Other computers get the same info from our router (DHCP) minus the IP address, and they work fine. When it is connected to any network (I've tried multiple different networks), it's as if the localhost is waiting for something before sending back any data. I've tried with and without firewalls. When unconnected, it works like a charm. Any ideas?
