Windows Update client does not fully support Microsoft's NTLM protocol.
I am using NTLM or Proxy authentication on Guardian, and Windows Office 2010 updates do not work. What can be done?
Windows updates and Office 2010 do not support the NTLM authentication protocol.
- Add the following to authentication exceptions:
- Who: Everyone
- What: SSL/CRL, Software Updates
- Where: Everywhere
- When: Always
- Action: Whitelist
If you continue to experience issues, filter the Web filter logs by the IP of a test client and attempt to open the site or application. Add the domains that appear in the Web filter logs to the authentication exceptions. You may need to create a custom category for these domains first.
