For test lab scenarios where you quickly want to add a few thousand users you can run the following batch files in a DC:
:Creates 10000 disabled user accounts with password Password1For /l %%t IN (1,1,10000) do net user BulkUser%%t Password1 /add /PASSWORDREQ:YES /ACTIVE:NO
:Bulk create 1000 groupsFor /l %%t IN (1,1,1000) do net group Bulkgroup%%t /add /domain
I received the following error when running the first command:
"%%t was unexpected at this time."
It sounds like you only copied the first line of the command - the second part is required also ("Password1 /add /PASSWORDREQ:YES /ACTIVE:NO")
Instead of %%t, use %t
