While connecting to Lotus notes database from dotnet application using Interop.Domino dll, I was getting the following error.  (“Retrieving the COM class factory for component with CLSID {29131539-2EED-1069-BF5D-00DD011186B7} failed due to the following error: 80040154”)

When i installed Domino Server setup we the issue was solved. But unforunately this will not roll out as we might have to run the migration application in different machines. After searching a lot i net i found an article in IBM site about a dll named nlsxbe.dll.

Once I registered this dll using regsvr32, i was able to connect to lotus database with just lotus client installation and Interop.Domino object.

nlsxbe.dll will be found in lotus notes installed folder. 

More to come on lotus notes migration, watch this space.
