NIC Speed

[Brian]

When ever sysprep is run it returns the NIC back to "auto negotiate". Is
there a way to prevent this from happening? or a script that could be run so
set the NIC back to "100 full duplex".
Thanks
Brian

Hi

A couple of previous posts about scripting the NIC settings:

Hi Brian,

The speed setting for NIC is quite different from NIC to NIC.

It is set by the inf file that used to install the NIC.

For example, the Intel(R)PRO/1000

%systemroot%\inf\nete1000.inf
Search Duplex
Find the [copper.reg] secion

; SpeedDuplex
HKR, Ndi\Params\SpeedDuplex, ParamDesc, 0,
%SpeedDuplex%
HKR, Ndi\Params\SpeedDuplex, default, 0, "0"
HKR, Ndi\Params\SpeedDuplex, type, 0, "enum"
HKR, Ndi\Params\SpeedDuplex\Enum, "0", 0,
%AutoDetect%
HKR, Ndi\Params\SpeedDuplex\Enum, "1", 0,
%10Mb-Half-Duplex%
HKR, Ndi\Params\SpeedDuplex\Enum, "2", 0,
%10Mb-Full-Duplex%
HKR, Ndi\Params\SpeedDuplex\Enum, "3", 0,
%100Mb-Half-Duplex%
HKR, Ndi\Params\SpeedDuplex\Enum, "4", 0,
%100Mb-Full-Duplex%
HKR, PROSetNdi\NdiExt\Params\SpeedDuplex, ExposeLevel, 0, "3"
HKR, PROSetNdi\NdiExt\Params\SpeedDuplex, MiniHelp, 0,
%SpeedDuplexMiniHelp%

Then go ahead to the regedit and find the following:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11C
E-BFC1-08002bE10318}\0001\Ndi\Params\SpeedDuplex\Enum

If all your machines are using the same NIC, you may find similar registry
settings from one machine and applied to all the other machines with a
simple .reg file.

HTH.
