To resolve the issue:

1. Open an MMC console and load the Certificate Manager Snap-In.

   

   

2. Load the Certificate Snap-in to the console using Computer Account and Local account.

   

   

   

   

3. Browse C:\Program Files (x86)\Trend Micro\OfficeScan Client and copy OfcNTCer.dat to a temporary location.
4. Rename OfcNTCer.dat to OfcNTCer.cer and open it to verify that the issuer is OfficeScan NTSG.

   

   

5. Import the OfcNTCer.cer into the Trusted Root Certificate Authorities in the MMC Console.

   

   

6. Verify after import that the OfficeScan NTSG certificate is in the Trusted Root Certificate Authorities folder.

   

7. In the MMC, go to Personal > Certificate Foldersand double-click the ofcsslagent certificate to verify that the chain is now complete.

   

The OfcNTcer.cer is common to all agents and a scripted import to the Trusted Root CA on the SSL agents will correct the chain.
