Last year I wrote a howto on howto hide local drives in a windows server 2000/2003 environement. Time past and Microsoft was busy building Windows Server 2008 which is currenlty in RC0.

Now we wrote another howto but this time for Vista and Windows Server 2008 edition working with the new admx and adml files. I am still learning the tricks with policies in windows server 2008 but thought let's already write a howto for it.

You can read the howto here
