I wrote a Online Document Management System for Company Intranet. When I try to Upload Files size More than 215MB it came up with the error "Application Unavailable" after some times. I configure Web.Config File for Max 1GB file Uploading and I change execution/Session time for resonably High values<BR>Pls Tell Me How can I avoid this Problem. I used Normal Compacq Compute with 512MB main memory as IIS Server
