We copy the install package to the c-drive of the computer.
Map c:\install\xxxx
Then in a job we run the installation from c:\install\xxxx\ (local system account)
Afterwards we delete the c:\install map.
We install like this because networktraffic can cause trouble while installing.
If during installation from the share there is to much traffic the job can be cancelled.
This works fine. You can even install multiple computers at a time.
