IIS help needed desperately
I'm setting up a new windows 2000 server and have run into a problem I've not had before.IIS is serving pages incredibly slowly

FTP is fast, mail is fast, even the pages in imail webmail are fast, but anything running from IIS is taking an age - literally minutes to load a page that shoudl take 10 seconds.
This is a brand new server ( I've been running another for a few months without incident ) with only 3 sites set up, each on their own IP and I need some help badly

Ta in advance . . . . .
