The DSProxy dll is required but cannot be loaded, error 'c00700c

This issue made me spend over 14 hours and I don't even want to begin to tell everyone how much I hate to see, exchange is installed on the domain controller (-:

The SA and the Information store insist not to comeup )-: Hirrrrrr everything else all other services were up and running, make sure the DSProxy.dll is there and register is pointing to right path as explain below KB.

When Path is correct re-start the SA and information store


HKLM\SOFTWARE\Microsoft\Exchange\Setup registry,key has the correct path of the DSProxy.dll file

  • Start Registry Editor.
  • Locate the following registry key: HKLM\SOFTWARE\Microsoft\Exchange\Setup and double-click the Services registry entry in the results pane.
  • Make sure that the Value data contains the following value: C:\Program Files\Microsoft\Exchange Server.
    Note   If you installed this Exchange server in a different location, make sure that the Value data contains that location.
