IIS7 file or directory error is not found when video is greater than 30M _win server

This situation occurs on systems that use IIS7 because IIS7 limits the size of the uploaded file and allows maximum upload of 30M by default.

Solution:
Modify Iis_schema.xml This file to first obtain the control of this document;
Enter directory C:\Windows\System32\inetsrv\config\schema, modify file Iis_schema.xml permissions:

Enter Iis_schema.xml file permission modification, select "Advanced"

Select "Owner"

Check Administrators OK

Then enter the permission editor, modify administrators Full control.

Then remove the read-only property of the Iis_schema.xml.

To modify a file configuration:
Then the search 3000000 meaning is only allowed to upload 30MB file size, you add a 0 after this to become 300MB should be enough. Then restart IIS 7

Copy Code code as follows:

<element name= "RequestLimits" >
<attribute name= "maxAllowedContentLength" type= "uint" defaultvalue= "30000000"/>
<attribute name= "MaxUrl" type= "uint" defaultvalue= "4096"/>
<attribute name= "maxquerystring" type= "UINT" defaultvalue= "2048"/>
<element name= "Headerlimits" >
<collection addelement= "Add" clearelement= "clear" removeelement= "Remove" >
<attribute name= "Header" Type= "string" required= "true" isuniquekey= "true" validationtype= "nonemptystring"/>
<attribute name= "SizeLimit" type= "UINT" required= "true"/>
</collection>
</element>
