Resolve attachments in IIS 6.0 that cannot upload more than 200K and cannot download more than 4M

  
In IIS 6.0, the default settings are particularly strict and secure, with a maximum of 204,800 bytes, which minimizes attacks due to previously too loose timeouts and limits. (There is no such restriction in versions prior to IIS 6.0) Solution: 1. Turn off the iis admin service in the service first. 2. Find the metabase.xml file under windows\\system32\\inetsrv\\. 3, open in plain text, find ASPMaxRequestEntityAllowed to modify it to the required value (can be modified to 10M ie: 10240000), the default is: 204800, namely: 200K. 4. Save the file and restart the iis admin service. In IIS 6.0, when you can't download more than 4M attachments, you can solve the following steps: 1. Turn off the iis admin service in the service first. 2. Find the metabase.xml file under windows\\system32\\inetsrv\\. 3. Open in plain text, find AspBufferingLimit and change it to the required value (can be modified to 20M ie: 20480000). 4. Save the file and restart the iis admin service.
