RPvdsEx crashes when used with OpenEx

Tech Note: TN0908
Product: OpenEx, RPvdsEx
Version: All
Date Added: 2012-10-16


Some security programs confuse third-party software background memory calls with fatal errors and force shutdown the program either without giving an error message or giving the message "The RPC server is unavailable."

On some, but not all HP computers, the HP Security Manager will allow RPvdsEx to work without error in standalone mode but will not allow circuits to open when RPvdsEx is attached to OpenEx. Microsoft support has identified this issue and offered the following solution.


To resolve this issue, you must disable a DLL for the HP Security Manager. To do this:

  1. Browse to C:\Program Files (x86)\Hewlett-Packard\HP ProtectTools Security Manager\Bin.

  2. Locate the DpFbView.dll file and rename the file, changing the extension from .dll to .old.
