PRB: Sample Gateway Fails to Start with a Logon Failure

• Exchange Development Kit (EDK), versions 4.0, 5.0, 5.5

SYMPTOMS

When you start the sample gateway, you may get an event ID in the application log that states the service could not start due to a logon failure.

CAUSE

This can be caused by having duplicate Ipm_in.dll and Ipm_out.dll keys in the registry.

RESOLUTION

Check these keys in your registry as follows:

1. Run Regedit.
   
   WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
   
   For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).
   
   
   
2. Go to the key HKey_Local_Machine\Software\Classes\Mapi Conversions. You should have the following two keys under this:
   
   

   Ipm_in.dll
   Ipm_out.dll
   
   

   You should not have duplicates of these keys.

STATUS

This behavior is by design.

MORE INFORMATION

Under the Ipm_in.dll key, there should be one key called GetTrivialVector. This key holds three values:

Classes: REG_MUTI_SZ: MESSAGE.IPM REPORT.IPM
OPTIONS: REG_SZ:
Point:REG_SZ:SAMPLEGW.INBOUND
