it is true. IIS6 runs on WS2003, only. So to get web services running on
iis6, you need ws2003.

no. it is not possible to install IIS 6.0 on Windows XP Pro.
but you can install IIS 5.1 on WinXP Pro and have a valid ASMX host. google
around for it. it's a typical config for developers and is fully supported.

yes, with IIS5.1 and .NET 1.1 on WinXP, you will be able to do this.

IIS 6.0 delivers a much more robust server-oriented process model. IIS 5.1
lacks this.
also, WinXP isn't licensed for high concurrency. I think 5 or 10 concurrent
connections. WS2003 can support thousands of connections. lots of other
differences, too.
