Issue/Introduction

The Symantec Endpoint Protection Support Tool reports that the Distributed Component Object Model (DCOM) is not enabled.

Cause

DCOM is a set of drivers that allows software communications over networks. The Symantec Endpoint Protection installation requires DCOM to be enabled and running in order to succeed.

  1. Click Start > Run, type regedit, and click OK.
  2. In the Registry Editor, go to:

    HKEY_LOCAL_MACHINE\Software\Microsoft\OLE
  3. Examine the string value EnableDCOM. If the string value is set to N, double-click it and change it to Y.
  4. If you made a change in step 3, restart the computer.
