If you configure Team Foundation Server 2010 (TFS 2010) to be accessible via the Internet, you may be using Forefront Threat Management Gateway 2010 (Forefront TMG), or its previous incarnation Internet Security & Acceleration Server 2006 (ISA 2006), as your reverse proxy. If you try to run Windows Update on your reverse proxy server you may get an error 0x80072EE2.
The cause for this is that Forefront TMG may have the Web Proxy feature enabled. By default this will be set to use port 8080.
If that’s the case, in order to allow Windows Update to successfully install updates you can try to configure the proxy settings in your Internet Explorer (IE).
To configure IE proxy settings:
- Load the Internet Options dialog
- Select the Connections tab
- Click on the LAN settings button
- Under the Proxy server section, enable “Use proxy server…” and specify Address: localhost, Port: 8080
- Click OK on all popups
You should now be able to complete your Windows Update requests.
