Thanks Daniel for your instructions!
There is no the problem when I start my computer in Safe Mode.
The problem reappears when I start my computer in Diagnostic startup mode
and in Selective startup with "Load system services" and "Load startup items"
unchecked. The "Group Policy Client" service starts in the Diagnostic startup
and in Selective startup modes with "Load system services" and "Load startup
items" unchecked. Its imposible to stop the "Group Policy Client" service or
disable it.
I installed Debugging Tools for Windows x64 from
http://www.microsoft.com/whdc/devtoo...g/default.mspx and then opened
Process Explorer, Options, Configure Symbols. Filled
C:\Program Files\Debugging Tools for Windows (x64)\dbghelp.dll
srv*c:\symbols*
http://msdl.microsoft.com/download/symbols
in that dialog box.
