Okay, I understand the issue better.
Determine whether you want to copy the drivers locally or to store them on a central distribution server. If you want to store the drivers locally on the computer's hard disk, you must have a method to copy the drivers to the computer (for example, by using logon scripts, Microsoft Systems Management Server batch jobs, or other methods).
After you determine the distribution method, obtain the path for the device drivers. If you want to copy them locally, the path may be C:\Drivers\Nic. If you want them centrally located server, the path may be \\ServerName\Drivers\Nic (where Drivers is a shared folder).
Update the DevicePath key in the local computer's registry to reflect the new OEM driver locations. You must have an automated method to remotely update the registry key. You can use Regedit files together with logon scripts or an SMS batch job. You can find the default value in the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\DevicePath: REG_EXPAND_SZ:%SystemRoot%\Inf
Use Regedit.exe to edit the DevicePath key so that path where the drivers are located is included in the search path.
For example, if the drivers are copied locally to the root of the drive on which the %WinDir% folder resides (Drivers\Nic), the DevicePath final value should read as follows:
DevicePath: REG_EXPAND_SZ:%SystemRoot%\Inf;%SystemRoot%\Drivers\Nic
If the drivers are kept on a centrally located server or distribution point, add the UNC path to the OEM-supplied drivers. For example:
DevicePath: REG_EXPAND_SZ:%SystemRoot%\Inf;\\ServerName\ShareName\Drivers\Nic
NOTE: %SystemRoot% is not automatically appended in the preceding case because the Setup process does not add the values. You must manually type the value of %SystemRoot% when you edit the registry.
After you have completed these steps and new hardware is installed, and then a user logs on, Plug and Play locates the new hardware and searches the device paths that you specified to locate the OEM-supplied drivers. Please note that all the rules that apply to signed and unsigned drivers also apply to devices installed after Setup. If the OEM-supplied drivers for the new device are not digitally signed and a nonadministrator user logs on to the computer after the new hardware is installed, the user cannot complete the installation of the device until an administrator logs on to the computer.
