ASP Error when configuring File Access within IAG

I was on site when I encountered an odd issue.  When configuring the File Access component within IAG, we got teh following ASP error:

Request object error 'ASP 0104:80004005'

Operation not allowed /whalefilesharingadmin/computers.asp, line 47

Thanks for Senthil from Celestix who found the answer to this.

The error was being caused due to the size limit in IIS for the maximum number of bytes allowed in the entity body of an ASP request.

The answer is to locate this file:

C:\Windows\System32\Inetsrv\metabase.xml

and modify the following value:

AspMaxRequestEntityAllowed to 1073741824

This changes the excepted size limit to 1GB.
