TcpUseRFC1122UrgentPointer

Hi, i am curious about this tweak

TcpUseRFC1122UrgentPointer
Key: Tcpip\Parameters
Value Type: REG_DWORD - Boolean
Valid Range: 0,1 (False, True)
Default: 0 (False)
Description: This parameter determines whether TCP uses the RFC 1122 specification for urgent data or the mode that is used by BSD-derived computers. The two mechanisms interpret the urgent pointer in the TCP header and the length of the urgent data differently. They are not interoperable. By default, Windows XP uses the BSD mode.

the default is BSD, but isnt it better to set it to RFC 1122 since most tweaks like RWIN and other things in XP are by RFC rules?

anyone willing to give any help/ info?

Cablenuts recommends it to 0 ....but to me it smells as if they read the DEFAULT of winxp and just use it to be safe. i wonder.

Nothing is for certain. But you can always use the tweak program to experiment and keep the setting that serves you better.
