I had to remove my USB wireless key from my server the other day to help build a friend’s machine. When I put it back in my machine I noticed that it had assumed another IP Address. When attempting to set the IP back to what it should be so that the router will forward web requests, I was given the conflict of IP addresses message. Initial investigation led me to this KB article.

I attempted this on my machine (Win 2003) but I couldn’t get any of the hidden items to show – I’m assuming that the KB article doesn’t apply to Windows 2003. The only solution I could think of at the time was to modify the IP address that the router forwards to, and modify the IIS configuration to listen for a different IP address. Another solution would be to remove and add TCP/IP – I cannot do this at present because I don’t have a screen to plug in.
