I'm about to put in a physical 2k8 R2 terminal server at the customer where we're seeing the most crashes, in case this is relevant. On possible factor is that all the 2k8 R2 terminal servers I've seen this on have been Hyper-V VMs (running on a 2k8 R2 host). We have a support case open with Microsoft, and the MS support engineer has conceded it's happening, but has so far been unable to find the reason. My question is has anyone else seen this, and if so any clues on what's happening? no anti-virus to confuse things, and we're still seeing crashes.
I have just today set up a brand new shiny 2k8 R2 terminal server with as simple a setup as possible, e.g. Maybe one time in four, and just to be really confusing, on a test server in my office I can't make it crash. Typically it crashes when you click File/Open or File/Save, but not every time. We are finding that Word 2007 (with SP2) crashes when used on a Windows 2008 R2 terminal server.
