Just some weeks ago I ended up in a situation where I needed to get a user SID (Security Identifier). I found a good script on the net that I just needed to modify a little.
Just log in as the user you need SID for and run this script:
"strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objAccount = objWMIService.Get _
("Win32_UserAccount.Name='xxxx',Domain='yyy'")
Wscript.Echo objAccount.SID"
replace xxxx with you user name and domain yyy.
Depending on your settings you'll get the output as alertbox or in the cmd.
