Follow this article to learn how you can fix ‘The Semaphore Timeout Period Has Expired’ error without taking help of a computer technician.

What Does the Error Actually Mean?

You may get this error because the Windows PC you’re using isn’t capable of downloading more than 50 MB of file online. Sometimes, your system may also present this error while uploading large files or if the uploading process takes longer than 30 minutes. Users accessing the Web Client in Windows 7 will confront this error while sharing files on an IIS Server. The error message will state the following information and stops the upload/download process immediately:

“Error: 0x80070079: The semaphore timeout period has expired.’

What is the Main Cause of the Error?

The main reason behind the error could be the setting of the Timeout Value, which is 1800 decimals, by default.

Tips for PC troubleshooting to Fix the Error using Microsoft’s Fix it

• Go to the Microsoft’s official website and click the ‘Fix it’ button

• Save the problem fix codes on your PC and right click on the file

• Now, click ‘Run’ option in the ‘File Download’ dialog box

• Follow the instructions in the ‘Fix it’ wizard to fix the error.

Some points to remember while fixing the error using Microsoft’s Fix It

  • The Fix it solution codes will increase the Timeout Value of the registry entry to 3600 (Decimal)
  • The wizard is available in English only, but you can access the automatic fix section to make it work for Windows editions in other languages as well.
  • If you’re accessing the Microsoft’s Fix It section from any other PC, save the Fix It solution to a removable media drive and run it on the problematic computer.

Tips for Troubleshooting the Error Manually

To resolve some of the PC problems, you’ll need to customize the registry entry. Since the error code gets generated because of the Timeout Value of the registry entry, you will need to make the following changes in the respective entry:

1. Click Start, type ‘regedit’ in the Search box, and press Enter

2. Click the following registry subkey:


3. Now, find the ‘DWORD FsCtlRequestTimeoutInSec’ section

4. Go to ‘Edit’ menu and click the ‘Modify’ option

5. Increase the ‘Value’ of 1800 (Decimal), from the ‘Value data’ box and exit the Registry Editor

6. Now, restart the Windows 7 PC to apply the changes.

Important Note:

Always remember that the ‘FsCtlRequestTimeoutInSec’ section is set to 1800 decimals, by default, and you can increase the setting beyond 1800 decimals. PC experts suggest increasing the value to 3600 (Decimal) to make your PC more compatible with low bandwidth networks.


The PC troubleshooting guide contains steps that require you to modify the registry entry to restore your device back to an error-free state. Always remember that you may face some uncertain errors and serious PC problems if you modify the registry incorrectly. Therefore, follow the steps mentioned above carefully or take help of an online PC support technician to fix the issue.
