This one is odd. Every couple of weeks, IIS just simply stops working. The services are all running and there are no errors logged. It just simply does not serve bytes.
Server 2003 SBS
IIS logging stops.
telnet server 80
- as soon as I type 1 character, it drops me back to command prompt.
netstat -ano shows that IIS is listening on port 80 and 443
If I stop IIS admin, then netstat shows nothing else on port 80, and telnet fails with "could not connect".
Restarting services does not fix it.
Only a reboot of the server fixes it.
