Batch Script Delete Folders & Files (Except One) From Remote PCs - batch-file

Question

We have multiple workstations that we need to do this on, and would like to batch script it (PowerShell is not an option for this particular task).
On each PC, we need to kill a specific process ("univmgr.exe"), then delete all subfolders and files from the following parent directory: C:\DRS\TEMP, except one subfolder named "DGNUser10" (as well as excluding everything inside the DGNUser10 subfolder).
I'm able to get my test script to work when I run it locally on a single test machine:
#echo off
taskkill /f /im univmgr.exe /t
pushd "C:\DRS\TEMP" || exit /B 1
for /D %%D in ("*") do (
if /I not "%%~nxD"=="DGNUser10" rd /S /Q "%%~D"
)
for %%F in ("*") do (
del "%%~F"
)
popd
But when I try to target a text file list of computers (list.txt), something is horribly wrong with my syntax, but I haven't yet been able to figure out what it is or how to fix it... Here's the current script I've been tweaking and testing:
:Start
cls
#echo off
for /f "tokens=*" %%A in (list.txt) do (
taskkill /f /im univmgr.exe /t
for /D %%D in ("C:\DRS\TEMP") do (
if /I not "%%~nxD"=="DGNUser10" rd /S /Q "%%~D"
)
for %%F in ("*") do (
del "%%~F"
)
)
Goto End
:End

Thanks to Squashman's gentle and spot-on leading, I was able to figure out what I needed to modify in my code in order to get the script working!
Here's the updated script:
:Start
cls
#echo off
for /f "tokens=*" %%A in (list.txt) do (
taskkill /s \\%%A /f /im univmgr.exe /t
pushd "\\%%A\c$\DRS\TEMP" || exit /B 1
for /D %%D in ("*") do (
if /I not "%%~nxD"=="DGNUser10" rd /S /Q "%%~D"
)
for %%F in ("*") do (
del "%%~F"
)
popd
)
Goto End
:End
