WDS Capture "Access Permission" Problem

Hello everybody!

Installed a 2008R2 Server with WDS und a Win7Pro Client. I syspreped the Client an cannot capture the Image.

For a couple of days a struggle with file Access Problems during the wds Client capture process.

Even if the targetfile is at the local disk, the capture process quits after 46% with an "Access denied" errorwindow.

Are there any *.log files, that could give me information, about the files that cause the problem?

I deactivated hibernate mode already, as the hibefil.sys made Problems - no Change yet.

Thank you for your answer

Robin
