I have written a Windows Service using C# which uses the lotus domino interop dll to communicate with lotus notes server and sends emails. It was working fine few months ago. When I rebuilt the solution, I received the following error:

Attempted to read or write protected memory this is often an indication that other memory is corrupt

_notesDataBase = _notesSession.GetDatabase(serverName, sMailFile, false);

Error occurs in the line specified above.

Additional info: I recently changed my lotus notes server password for my mail box.As I figured out that might be problem in ID file of lotus notes?

Out of sheer morbid curiosity - why did you go through the bother of making a screenshot, rather than copy-pasting your code? – J. Steen
I am connected to a remote machine.It would be lot simpler if you take screenshot. – Jeyaganesh
I took the liberty of typing it out for you. – J. Steen
Can you capture and post the full stacktrace for this error? – Richard Schwartz

I had the same issue!
When Session.GetDatabase() get called the exception gets thrown in one of it's sub Threads, making it nearly impossible to findout what is actually causing the Problem.

Here is what helped me:

  1. Deinstalling Lotus Notes
  2. Backing up my local Database files
    This website should give you a good overview on what might be important to keep. It is in german but it should help never the less.
  3. Deleting Registry entries
    I deleted entries under HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER.
    Just look for Software and you should find IBM there.
    Some more IBM stuff was hidden in HKEY-LOCAL-MACHINE --> SOFTWARE --> Wow6432Node.
  4. Reinstalling Lotus Notes

This wrapped up the problem for me nice and neatly.
The real source of the bug is yet to be discoverd...

EDIT:
It's enough to run the installer and select repair.
