Gigabit Network problems with 2003 Server

Gigabit networks and 2003 do not always work together first time. Quite often an error will apear in the event log which is detailed below. This error has a major affect on the active directory and will also slow down the network; negating the point of having gigabit!

Event Id: 1054

Description:
Windows cannot obtain the domain controller name for your computer network. (The specified domain either does not exist or could not be contacted. ). Group Policy processing aborted.

Microsoft have put this problem down to having Media Sense enabled on your nics. To fix this problem you need to disable Media Sense and to do that, you need to modify the following registry value:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters

Add in a new DWORD value called DisableDHCPMediaSense

Give it the value of 1 to disable Media Sense


Hope this works!
