Of Endpoints, CTPs, and Virtual PC

I’ve spent the better part of this week working with HTTP.sys endpoints in Yukon – well trying to. On my notebook nothing I tried would create the endpoint. On other machines the code would run great but not on my machine. I learned that XP SP2 still uses IIS 5.1 which listens directly and therefore can conflict with the kernel HTTP.sys when also listening on the same port. Nevertheless, switching ports did not solve the problem. I suspect that the problem is that I’ve uninstalled and reinstalled various CTP versions of Yukon one too many times. So running a clean new copy of Windows Server 2003 and the June CTP under Virtual PC is the only way I’m moving forward. And in this configuration, the HTTP endpoints run smoothly.
