These errors are generally the result of an antivirus or firewall  program that prevents the Windows Update software from functioning properly.

To troubleshoot the issue, temporarily disable the firewall and/or antivirus program. If this resolves the problem:

- You may want to contact the vendor for instructions.

- Make sure TCP/IP ports 80 and 443 are open in both directions.

- Make sure the firewall isn't blocking scripting functions on Web sites.
