Exchange 2013 built-in anti-malware: MS Filtering Engine Update process was unsuccessful in contacting the Primary Update Path

Issue: Exchange 2013 cannot download anti-malware updates

Event Viewer error:
MS Filtering Engine Update process was unsuccessful in contacting the Primary Update Path. Update Path:

·        Source: FIPFS
·        ID: 6027
·        User: Network Service

Exchange 2013 server:

·        The Exchange 2013 server has Internet access and can access path:
·        Exchange installed on D: drive
·        Exchange 2013 CU9 (Multi-Role) on Windows 2012 R2

“If the above will not resolve your issue check that "NT AUTHROITY\Network Service" has full access for the folder Program Files\Microsoft\Exchange\V15\FIP-FS\Data\Engines\amd64\Microsoft\bin, in case you have installed Exchange in different drive, you need to add "NT AUTHROITY\Network Service" on the drive itself.”

My ‘solution’:

·        Browse with File Explorer to D:\Program Files\Microsoft\Exchange\V15\FIP-FS\Data\Engines\amd64\Microsoft\bin
·        When accessing FIP-FS directory (and some other subdirectories) File Explorer displays a dialog box that prompts you with the following: You don’t currently have permission to access this folder. Click Continue to permanently get access to this folder.
·        After clicking Continue you are able to browse directory contents
·        NTFS security permissions on D:\Program Files\Microsoft\Exchange\V15\FIP-FS\Data\Engines\amd64\Microsoft\bin show NETWORK SERVICE with appropriate permissions

After performing these steps anti-malware updates are being downloaded.

  1. Thank you for sharing the actual Solution!

  2. Thank you for sharing! Your solution is so much simpler and straight forward vs Microsoft's.

  3. I have been using Kaspersky Anti virus for a number of years now, and I would recommend this solution to all of you.

  4. Be that as it may, while all are great, at some point this web can drag us amidst real inconveniences also. After all it is a direct result of the web itself that all the different infections assault us.
