Hi proffy,
IIS7 and large files By default in IIS 7 requestFiltering has the MaxAllowedContentLength property enabled. It specifies, in bytes, the maximum length of the content in a request. The default is 30,000,000 (approximately 30 megabytes.) To change this value you must edit the following file:
%windir%\System32\inetsrv\config\applicationHost.config.
In the ApplicationHost.config file, locate the <requestLimits> node.
Modify the following code.
<requestLimits maxAllowedContentLength ="10000000" />
You can try value "900000000"(900MB)
<requestLimits maxAllowedContentLength ="900000000" />
Regards,
Ken
