Batch File: It will locate a node and provide the username of currently logged into that node

Question

Okay here's another one.

So the idea for this batch uses two loops, but I feel like I lack the proper knowledge but here we go:

Batch code: (Please be advised, that when user's are assigned computers, they are assigned by the description. Not my choice but anyway, it searches for computers owned by the description.)

    @echo off
    echo First and Last Name of User:
    echo.
    set /p name= 
    set desc="assigned to %name%"
    echo.
    dsquery computer domainroot -desc %desc%*
    for /f "delims=," %%a in ('dsquery computer domainroot -desc %desc%*' ) do set CompName=%%a123
    set CompName=%CompName:~4,-3%
    pause
    for /f "delims=" %u in ('wmic /node:%CompName% COMPUTERSYSTEM GET USERNAME^|find "\"') do set userfound=%~nxu
    pause

The batch seems to break at the second loop. I feel as though maybe because the first loop that is assigned a variable, it won't allow for a second for /f command to run properly.

Any suggestions?
