– Starting the Scense Client will show an Executive problem message
– The debug log shows “Error: (-2147023175) Automation error” while trying to communicate with the Scense Engine
– The scense Diagnostic tool shows the “Error: (-2147023175) Automation error” message while trying to comunicate with the Scense Engine


This problem occurs because of improper configuration of the port range settings in the HKEY_LOCAL_MACHINESoftwareMicrosoftRpcInternet registry key or because the port restrictions for a protocol are configured through the DCOMCNFG protocol property page.

The decimal presentation (-2147023175) equals the hexadecimal presentation (0x800706b9) of the error message. The message means: “Not enough resources ae available to complete this operation”

To easily convert the decimal- to the hexadecimal presentation use the calculator in Scientific mode (Windows XP) or Programmer mode (Windows 7). Simply copy and paste the decimal value (incl. the minus sogn) into the calculator. Switch to Hexadecimal view and use unly the rightmost 8 characters.
