Hello,

I have work on a little network script to run Boinc from a Windows using Administrative share, using different data directory set as running BOINC computer name.
In my case, BOINC was on D drive in BOINC directory.

Could not work on first run but is OK at 2nd.
Shouldn't leave trace on computers.
Running from network can slow tasks.
Running from network can increase network use.
