Recently I had to get an old ASP application working in IIS 7.5 on a W2K8 server. Almost everything works fine, except that I can\'t seem to get it to accept uploads larger
On Windows 2008 - Go into Administrative tools - server Manager - expand Roles - expand Webserver -click on IIS - and look for the web instance, for which you want to change the file size limit and then go into option “ASP” expand “Limit properties” and property you need to change is 'Maximum Request Entity Body Limit'. File Size is always in bytes so use any online calculator to calculate the conversion of bytes to KB or MB.
