Question

I am running 3 virtual machines that are running tests using cc.net server. Currently tests are running simultanously on 3 machines. All the tests require to access Excel file. When tests run individually they all work fine but running them on virtual server is causing this error. Any idea how to resolve this issue.

I just had the same thing happen. This morning I ran a test application I wrote a few years back, then an hour later I tried to run anoter test and this error popped up. What the ...? Perfomed a hard reboot to no avail. I am now looking for the same answer as to what caused this.
