60 x "w3wp.exe*32" processes open

Hi,

Checked task manager and checked the "show processes from all users" option
and appear to have 60+ w32pm.exe 32 processes running.

I wont have that many users connected to my site, how can I figure out what
is uses these processes ?

My asp.2.0 app refreshes/updates every 5 seconds from sql db , could this
have something to do with it ?

note: 64 bit 2003 standard edition.

Thanks for any help
Scott
