Summary

Starting with OfficeScan 10.6 Service Pack 3 (SP3), Trend Micro has used Comodo certificates for digital signature verification.

If the OfficeScan server and client have Windows update disabled or are placed in isolated network environments, it may not obtain Comodo certificates for their trusted certificate store.

For the OfficeScan server and client machines which do not have these certificates, the following issues may occur:

  • You are unable to install the ActiveX components of the OfficeScan web console, which makes it inaccessible.
    A prompt says that the AtxEnc.cab is signed by an Unknown Publisher and the file is blocked because it does not have a valid digital signature that verifies its publisher.
  • OfficeScan clients remain in "Updating" state and fail to get their updates from the server.
  • The OfficeScan server cannot verify the agents' digital signatures during Inter-Process Communication (IPC).
