So, I had a chance to get back to testing Sysprep with Avast installed. I first thought it had to do with windows deployment services after sysprep was run, I now see the if happens after sysprep has been run and before it has been captured by WDS.
This is what I have done for testing so far, I installed
Windows 7 professional 32 bit from DVD, installed all system drivers, device manager shows all drivers installed properly, installed Avast from Admin console, successfully.
No windows updates: Sysprep/Oobe/Generalize/Shutdown.
I then start the pc back up and let it go through the setup process as if I just imaged the machine. Again, it goes through the process until it gets to “Setup is starting services” then halts with “Windows could not finish configuring the system. To attempt to resume configuration, restart the computer.”
I have done this twice with no change to the error message. On a 3rd restart, for testing, I started the pc up in safe mode, watched as drivers load, saw aswrvrt.sys load, system hung, error message stated cannot continue with setup in safe mode, restart the computer, at which point I did so.
The pc started up and goes through the first time set up, this time it completes and lets me name it, and join it to my domain.
As another test, I did the same but with
Windows 7 Pro 64 bit from DVD on the same pc, this time first run setup completed successfully without error. All this testing is done on a Dell Latitude E5530.
I repeated all this on a different pc, this laptop is a HP Probook 6555b with the same results, 32 bit OS errors out w/ Avast, 64 bit OS sets up w/o errors. As a last test, I went to Avast’s website and downloaded the standalone client for Avast! Endpoint Protection Suite 8.0, which is what we are using, the results were the same.
Repeated the whole process w/o Avast installed and both systems set up properly with no errors. Hopefully this helps clarify my process.
P.S.
I found out you can’t run debugging mode during first run setup.
