Windows: Local account management

To create a local user massively in a list of servers, you can use this command:

Psexec \\server1 net user user01 Pass.128 /ADD

Psexec \\server2 net user user01 Pass.128 /ADD

...

Use the excel to concatenate the fields, so you can have a full list of command, without typing each server.

Then, add the propper permission:

Psexec \\server1 net localgroup administrators /add user01

Psexec \\server2 net localgroup administrators /add user01 

...

If  you just want to allow access to a domain user, is pretty similar:

Psexec \\server1 net localgroup administrators /add contoso\user02

Psexec \\server2 net localgroup administrators /add contoso\user02

...

Then if you need to remove permissions, issue this command

Psexec \\server1 net localgroup administrators contoso\user02  /delete
