I have an odd issue that I'm at a loss to figure out. On the network here I have a web server (Win2k3) and an AD/DNS/DHCP server (Win2k8). Whenever there is a power 'blip', the web server goes off line and won't respond. When I go to the server room all I need to do is to log in (it's sitting at a command prompt) and it's fine.
The servers are on a UPS, but the network gear is not (switch, router, firewall, etc)
The AD/DNS server has nothing in it's log except for the NIC card being disconnected for 3 seconds. The web server (the problem child) has the same NIC notification and several 'Application Popup: Low Battery' warnings.
There is nothing wrong with the battery, it has 8 minutes of runtime if the power fails; and that's fine for me. If I unplug the UPS it picks up the load just fine.
So... a blip in the power causes the web server to go to a login prompt and it won't server web pages until I physically log in. No screen saver is configured.
