INV: Timeout Errors Accessing Web site

PSS ID Number: Q174614 Article last modified on 11-18-1998




The information in this article applies to:

  • The Microsoft Network, versions 2.0, 2.5
  • MSN MoneyCentral
  • Microsoft Internet Explorer versions 3.0x, 4.0x for Windows NT 4.0
  • == Microsoft Internet Explorer versions 3.0x, 4.0x for Windows 95 ==


When you navigate on a Web site you may receive a timeout error message similar to the following example:

Internet explorer cannot open the site “”. Operation timed out.


This issue can occur if Domain Name Server (DNS) Caching is turned off.


To resolve this issue, turn on DNS Caching. To do this, follow these steps:

  1. Download the Timeout.exe file from the Microsoft Software Library:

~ TimeOut.exe

For more information about how to download files from the Microsoft Software Library, please see the following article in the Microsoft Knowledge Base:

  1. Save the Timeout.exe file to a folder on your hard disk, and then double-click the Timeout.exe file to extract the following three files:

    • DnsOn.reg - This registry file turns on DNS Caching

    • DnsOff.reg - This registry file turns off DNS Caching

    • Readme.txt - This text file contains information about how to use the registry files.

  2. In Windows Explorer, open the folder where you extracted the files.

  3. Close your browser, if it is open.

  4. Double-click the DnsOn.reg file to turn on DNS Caching.

  5. Restart your browser and connect to the Web site that was having problems.

NOTE: If you need to turn off DNS Caching, double-click the DnsOff.reg file.


The default setting is to have DNS Cache enabled. AOL 3.0 for Windows 95 is known to disable the DNS cache globally by setting the DnsCacheEnabled registry key to zero (false). The DnsCacheEnabled registry key is located in the following registry key:


If you change the setting to one (true), then you enable DNS Cache. DNS Caching allows the system to store the resolution of DNS names to their actual Internet Protocol (IP) addresses without resolving the Host name each time. This cache is cleared each time you restart your system.
