I'm really at my wit's end right now. Every bloody time i heavly demand my server's (specs down below) network capacities, it freezes completely. No I/O-reaction, no work going on in the background, no network-communication, no events triggered or caputured in Window's event log. However, the machine's still running if it occurs, the fans keep spinning and no bluescreen shows up.
Sometimes a simple download does the job, sometimes accessing it parallel to that (e.g. streaming a movie) triggers this.
I was only manage to sort this out by plugging in a computer monitor (which apparently is quite unusual for a server).
I'm using the following machine:
Intel Celeron G540
8GB DDR3-RAM (2x 4GB)
ASUS P8H61-I LX R2.0
Samsung HD204UI + 3 other HDDS, even though this is the main storage-device
Fractal Design Array R2
Windows Home Server 2011
Every driver is up-to-date, except for a so-called "PCI communications controller" which i wasn't able to identify so far. But since I don't use any PCI device, I don't suppose that this has anything to do with my problem.
