I am using IIS6.0 on a Windows 2003 SP3 VPS.
When I access an ASP.Net website on that server, i.e. http://website.example.com/ it takes over a minute to load. If I load a standard website that's just HTML, it loads instantly.
Once the site has been successfully opened in one browser on a machine, all the other browsers can open the page straight away.
If I leave it for approximately 30 minutes I have to wait a long time again to load the site. I've tried this on 5 different machines on 3 different Internet connections. Each different machine has to wait for the site to load, even when another has already opened it.
The ASP.Net sites I am testing are single pages, with no actual code. The page should load in about 0.25s on a 2Mb/s connection.
Any ideas what's wrong with the server to cause this behaviour and how can I fix it?
I nuked the server and started it again with a new image. The same thing happens with 2 different asp.net websites that both load instantly on another server when tested.
