ASP .Net Web Form or Windows Form

[rodrick]

I'm just wondering if any one can explain to me when you would use an ASP .Net Web form instead of a Windows Form.
I have this guy at work who thinks that ASP .Net Web forms are great and thinks all applications should be developed. But I think that their are times when a Windows form would be better for the job.

So can someone let me know whether Web forms are the bees knees and should be used all the time or if there are circumstances a Windows form would be better please explain.

All the applications we develop are used inhouse so they're not being developed for release on the internet just over the network if that makes any difference.

Thanks
