IIS 6 File Upload Size Limit

Hi All,

We are running WC 9.1 M062 on a Windows 2003 64 bit server with IIS 6. The issue we are having is that users cannot upload files via the application server into the master vault larger than 30 MB. Out remote file servers are running Apache and they do not have this problem. I've researched the MS Knowledge Baseand have applied all the updates I can find but I can't seem to crack this nut. Is anybody else running IIS 6 having this problem?
