I'm nearly ready to smash my foot trying to figure this out...though I'm sure there's a simple explanation, but I'm simply not finding it! I have a Mac Mini Server running Snow Leopard Server on it. I have the strangest issues as it sometimes works perfectly, and then 10 minutes later it doesn't work at all. Right now if I go into Server Admin it shows "Available Servers (0)" rather than 20 minutes ago when it showed 1 available which is the server. I can't find anywhere that would point to it being unavailable. This seems to be so strange as I can point my iCal to a calDEV account on the server and have it work, go get lunch and come back to a computer full of errors saying that the server is no longer available. Please tell me I'm missing something!!!!
