@nikhilb There are few ways to do this between the machines.. This all assumes they are on the same network.. (can speak to each other over SMB).
Assuming they are on the same physical network, you can use psexec.exe and pass the credentials into it.
I’d create the batch file to handle both steps together.. (it will require the password to be embedded in the file for the new user).
net user <username> <password> /add /description "local user"
net localgroup administrators <username> /add
So, assuming your computer text list is just that.. this should work.
psexec.exe @computerlist.txt -u <username> -p <password> -c newlocaluser.cmd -accepteula
You may need to prepend in front of each computername in the file (Its been a long time, I just don’t remember).. If you don’t want to bother, then you could do it this way:
for /f %f in (computerlist.txt) do psexec %f -u <username> -p <password> -c newlocaluser.cmd -accepteula
Another way would be to use your account to copy the batch file on to each of the systems and create a scheduled task to run the batch file with the system account.
for /f %f in (computerlist.txt) do schtasks.exe /create /tn CreateLocalUser /tr c:newlocaluser.cmd /s %f /ru "NT AuthoritySystem" /z /st 14:00
The 14:00 would be whatever time you want it to run, maybe 2-3 minutes after you start it? and then when complete, delete the batch file so you don’t leave the stored password out there.
If you want to make this more secure.. then you could add randomized passwords to your text file, and make it comma delimited. If you go that route, you won’t need the batch file to copy, just 2 passes with psexec.
for /f "tokens=1,2 delims=," %f in (computerlist.txt) do psexec -h %f -u <username> -p <password> net user <username> %g /add /description "local user or whatever text"
for /f "tokens=1,2 delims=," %f in (computerlist.txt) do psexec -h %f -u <username> -p <password> net localgroup administrators <username> /add
This is the most secure version since you won’t be leaving the password in plaintext to the accounts on the servers themselves.
