Copy Local Policies to other machines...

Here's how I have done it / seen it done

1. Configure the local policy on one machine
2. Copy the %systemroot%\System32\GroupPolicy folder to somewhere on the network / your distribution share / whatever
3. On each target machine, assuming the 'master' GroupPolicy directory is located at D:\GroupPolicy, do

attrib -H %systemroot%\system32\GroupPolicy
xcopy D:\GroupPolicy\* %SystemRoot%\system32\GroupPolicy /e /v /c /i /h /r /y
attrib +H %systemroot%\system32\GroupPolicy

Reboot the target machine and all should be well.
