Alright... we're going into serious pocket-protector territory here, but the TCP/IP Registry Values for Microsoft Windows Vista and Windows Server 2008 guide is available for download.
If you have been just dying to know how to configure the W2K8 TCP/IP stack to use either RFC 793 or RFC 1122 to interpret the value of the Urgent Pointer field in the TCP header... (and why wouldn't you?) while now you can! Some of the gems included look like:
Value Type: REG_DWORD—Boolean
Valid Range: 0, 1 (false, true)
Default: 0 (false)
Description: This value determines whether TCP uses RFC 793 or RFC 1122 to interpret the value of the Urgent Pointer field in the TCP header. RFC 793 defines the value as indicating the first byte of normal data. RFC 1122 defines the value as indicating the last byte of urgent data. These two interpretations are not interoperable. Windows Vista and Windows Server 2008 TCP/IP defaults to the RFC 793 interpretation (used by BSD-derived systems).
Try using some of those sentences at a bar sometime! See how that goes for you 😉
