IIS 7 on Vista does not limit the number of allowed connections as IIS on XP did but limits concurrent requests to 10 (Windows Vista Ultimate, Business, and Enterprise Editions) or 3 (Vista Home Premium). Additional requests are queued which hampers performance but they are not rejected as with XP.
This is what I got from wiki, but I wonder how does it work in Win7?

No limit in Win 7 at all. Sensibly.
One assumes no retrograde step from this
Edit:
Of course, the limit in XP is applied before any IIS limitations. With Win 7 and later versions, the only bottleneck is IIS and not the half-open tcp limit.
