Changing "pre-Windows 2000" group name with ADModify.

I have 2000+ groups in AD where the (pre-Windows 2000) group name looks like random generated characters. I am lucky enough to have an application that still uses this name. Here is my fix.

Run ADModify and select Modify Attributes. Select a domain and domain controller. Show only Groups and Containers. Find the groups that need to be changed. Select the Custom tab and fill the blanks like below.

20 seconds to change 2000 groups!
