I had an old NT 4 server box running iis with a small intranet site on it. This thing ran rock solid for a very long time until about a month ago. I started having trouble connecting to the web page it was hosting (page not found or a timeout), but the box was up and I could still ping it, and I could physically go to the box and get out to the Internet. I thought maybe it was an issue with the combination of hubs/switches I was using, so I replaced them with new switches. No dice. Maybe a funky NIC or system board? A good enough excuse to upgrade the box, so I threw win2k server on a new box and moved the site over to it. Everything looks good, clean box, new hardware. I connect to it and away we go - for about 5 minutes. Then I again can’t connect to it. I can’t connect to the site it hosts, nor can I connect to it through terminal services. I can’t ping the box either. But, if I go to the server and open IE, it connects to the web no problem, and then I can go back and connect to it from any other machine with no problem. For about 5 minutes (the time isn’t exact – it could be 3 minutes, it could be 15). Any help would be greatly appreciated.
