You'll find the speed/duplex information under the vendor specific registry key. For example, for the Broadcom NetExtreme Gigabit adapter: HKLM\System\CurrentControlSet\Services\b57w2k\parameters Usually, you can figure out what a registry value means by changing your settings and refreshing the Registry Editor. A lot of new adapters will have a binary value called "SpeedDuplex". That's a good place to start. ______________________ Minesh Pandya Network Analyst Barlow Lyde & Gilbert LLP MPandya@xxxxxxxxx +44 207 643 7629 http://www.blg.co.uk "Dowdle, Ian" <I.J.Dowdle@xxxxxxxxxx> Sent by: gptalk-bounce@xxxxxxxxxxxxx 07/12/2007 09:23 Please respond to gptalk@xxxxxxxxxxxxx To <gptalk@xxxxxxxxxxxxx> cc Subject [gptalk] NIC settings Is there any way to set network cards to work at 100Mb Full duplex with a GPO? *********************** You can unsubscribe from gptalk by sending email to gptalk-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field OR by logging into the freelists.org Web interface.
