Latest Message<\/th>\nTitle: Admins may be unable to download Microsoft Defender Antivirus definition updates from the alternate download location<\/p>\n

User impact: Admins may be unable to download Microsoft Defender Antivirus definition updates from the alternate download location.<\/p>\n

More info: When admins attempt to download Microsoft Defender Antivirus definition updates from the alternate download location (www.microsoft.com\/security\/encyclopedia\/adlpackages.aspx?action=info<\/a>), they may have received an error that stated the following:<\/p>\n

“0x800704e8 The remote system was not available.”<\/p>\n

Admins could still have downloaded package updates using Microsoft Update in the Windows operating system.<\/p>\n

Final status: We’ve identified an authentication component, which is necessary for facilitating Microsoft Defender Antivirus definition updates through the alternate download location, which contained a misconfiguration that caused impact. We’ve corrected the misconfiguration and confirmed through internal testing that the impact is remediated.<\/p>\n

Scope of impact: Any admin attempting to download Microsoft Defender Antivirus definition updates from the alternate download location may have been impacted.<\/p>\n

Start time: Saturday, July 5, 2025, at 5:08 PM UTC<\/p>\n

End time: Monday, July 7, 2025, at 4:16 PM UTC<\/p>\n

Root cause: An authentication component, which is necessary for facilitating Microsoft Defender Antivirus definition updates through the alternate download location, contained a misconfiguration that caused impact.<\/p>\n

Next steps:
– We’re reviewing the affected authentication component to determine how the misconfiguration was introduced, so that we can prevent similar impact from occurring in the future.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
