Windows Defender was unable to complete the update 0x80072efd

When I click "check now" button, I see the above message.

Already tried removing sig file:

run - Msiexec /x {A5CC2A09-E9D3-49EC-923D-03874BBD4C2C}

Also tried uninstalling Defender completely, and re-installing.

I'm running fully patched XP.

I'm not behind any funky firewalls or anything. Old Microsoft
anti-spyware was always able to retrieve updates without issue.

Any other ideas?

thanks.
