Vista's TCP/IP Promises and Perils

boyko.at.netqos tips us to a new writeup on Vista's TCP/IP stack, which is called Compound TCP/IP (CTCP). From the article: "...security policy will come from a centralized source. When you get your DHCP lease, your computer will report to the stack what OS you're using, what version level, what patches, what anti-virus software that's active — all that kind of stuff. It will have the ability to restrict your network access if you have a down-level machine... We could see a lot of our customers with much higher WAN network utilization because of this new TCP/IP stack... CTCP can be enabled/disabled from the command prompt but there has been no mention of tuning parameters which leads us to ask the question: How are you supposed to configure this setting in Vista?... What worries us... is that Microsoft is basing this on packet round trip time. The round-trip time from the client-side will have the server processing time in it; but the clients aren't likely going to be the running the CTCP at first. If you have a server-to-server backup running, for example, CTCP may think its part of the round-trip time and it'll throw the delay window through the roof..."

    So then no worries, right? The first virus I get will surely disable CTCP for me, no sweat...

    Will be pulling their hair out when they try to mooch wifi from my hacked router. No matter what they do it will say they are unpatched
