Notes/Domino 6 and 7 Forum : unable to load the information service nwnsp.dll

An unexpected error has occurred. MAPI was unable to load the information service nwnsp.dll. Be sure the service is correctly installed and configured.

Office 2000 SP3
Lotus Notes 6.0.2 CF2
installed in that order.

Lotus Notes to default mail client. selecting MAILTO: links in web pages is fine and lauches Outlook.

We have a third party application (Pivotal) which needs to be able to send mail using MAPI.

I have read and reviewed all the technotes for this, although none are for ND6, all refer to R4/5

Basically you need to have that DLL (nwnsp.dll, which is actually nwnsp32.dll, but the "32" is ignored in the mapisvc.inf file) in your system directory, plus all the appropriate lines added in your mapisvc.inf file. They are all there.

The inf file should be here C:\Program Files\Common Files\System\Mapi\1033 (but it is also here, with the correct entries C:\WINNT\system32)

I have even tried explictly listing the path to that DLL in the INF file, i.e. C:\WINNT\system32\nwnsp.dll

Any other suggestions...
