Leave Domain: “A general network error occurred’

KB ID 0001738 Problem After a recent lab on the test bench, I ended up with a 2008  x32 standard server. It took me a while to get this setup and running, so I wanted to keep it (or turn it into a VMware template should I ever need  another). But first I needed to ‘remove it’ from  the domain it was in.

Apply Group Policy To a Security Group

KB ID 0001653 Problem On EE this morning someone asked how to map a drive to only two users, so that wherever they logged in, they got their mapped drive.
