Scripting

Any one succeed installing it without losing the network connection?
When I am trying to install Intel Proset 12.2, at a moment the computer is losing his network connectivity and then the batch is just kick out.

What I tried:

xcopy nic %systemdrive%\nic /E /Y /I > nul

pushd.
%systemdrive%
cd\
cd %systemdrive%\nic\APPS\PROSETDX\Win32
I tried:
::%noya%\Toshiba\TecraA9\nic\APPS\PROSETDX\Win32\DxSetup.EXE /qn /liwea %temp%\proset.log ANS=1 BD=0

I also tried this:
::DxSetup.EXE /qn /liwea %windir%\temp\proset.log ANS=1 BD=0

And also this one:
msiexec.exe /i PROSETDX.msi BD=0 ANS=1 TRANSFORMS=1036.mst /liwea %windir%\temp\proset.log /qn

popd

Any suggestion would be appreciate.
