Slow/Unreliable network with XPe

I've noticed that I tend to have slow or unreliable networking when using
Windows XPe. There are many times where systems will not autonegotiate to
use full duplex. Instead, they'd be using a half-duplex mode. Most of the
systems I use have 3Com or Intel based NICs.

Is there an easy way to force XPe to use full duplex for the connection? Or
is this a known issue that has a fix or workaround?

Any help is greatly appreciated!
 
Hi,

If I remember correctly the easiest way to do this is to add line in inf file that will set required value to what you want. (This
will be done for all network device instances in case of more net adapters).
Other way would be to create application that would be called during the FBA. You will have to know little about SetupAPI to find
adapters and change registry values.

GoldenEgg,

Try this experiment.

Go to the "Workstation Service" component's Registry Data section and change the following registry value to 0 (default is set to
1):
[HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters],"enablesecuritysignature".
See if it helps.

Also, toggle the TCP delayed ACK timer (TcpDelAckTicks) to a lower value. Just add the value at runtime under
[HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<Interface GUID>]. If you set the TcpDelAckTicks value to 0, you
turn the timer off completely.
