Troubleshooting IIS File Download Hangs and Timeouts with sc-win32-status = 64
IIS, or Internet Information Services, is a web server application developed by Microsoft for Windows operating systems. It is widely used for hosting websites, web applications, and services. However, like any software, IIS can encounter issues and errors that can affect its performance. One common problem that IIS users may face is file download hangs and timeouts with sc-win32-status = 64. In this article, we will discuss what this error means and how to troubleshoot it.
First, let's understand what sc-win32-status = 64 means. SC-WIN32-STATUS is a status code that indicates the reason for a failed request in IIS. The value 64 corresponds to the error code ERROR_NETNAME_DELETED, which means "The specified network name is no longer available." This error can occur due to various reasons, such as network connectivity issues, server misconfiguration, or corrupted files.
Now that we know what the error code means let's look at some possible solutions to troubleshoot the issue.
1. Check Network Connectivity
The first step in troubleshooting any network-related issue is to check the network connectivity. Make sure that the server hosting IIS is connected to the network and can communicate with the client requesting the file download. You can use the PING command to test the connectivity between the server and the client. If the server is not reachable, there could be a problem with the network configuration or the server itself.
2. Verify Server Configuration
Next, check the server configuration to ensure that it is set up correctly. Make sure that the website or application using IIS is configured to allow file downloads. You can check this by going to the IIS Manager and selecting the website or application in the left panel. Then, in the right panel, click on "Handler Mappings" and make sure that the "GET" verb is enabled for the file type you are trying to download.
3. Clear the Server Cache
Sometimes, the server cache can cause issues with file downloads. To clear the cache, go to the IIS Manager and select the website or application. Then, in the right panel, click on "Output Caching" and select "Stop Caching" for the file type you are trying to download. If this does not resolve the issue, you can also try clearing the cache for the entire website or application.
4. Check File Permissions
If the above solutions do not work, it could be a problem with file permissions. Make sure that the user requesting the file download has the necessary permissions to access the file. You can check this by right-clicking on the file and selecting "Properties." Then, go to the "Security" tab and make sure that the user has at least "Read" permission.
5. Disable Antivirus or Firewall
In some cases, antivirus or firewall software can interfere with file downloads in IIS. Try temporarily disabling them and see if the issue is resolved. If it is, you may need to add an exception for IIS in the antivirus or firewall settings.
6. Check for Corrupted Files
If the file download hangs or timeouts with sc-win32-status = 64, it could be due to a corrupted file. Try downloading a different file and see if the issue persists. If it does not, then the original file may be corrupted. You can try re-uploading the
