Unable to load the information service nwnsp.dll

HCL Domino Domino Forum

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…

You’ve run into a problem with R6 and later versions of Outlook. This problem will be fixed in 6.5.1/6.0.4

The workaround is to edit the file in C:\Program Files\Common Files\System\Mapi\1033\mapisvc.inf and merge the info from c:\windows\system32\mapisvc.inf into it.

The current Notes installer cannot detected the correct location of the MAPI DLLs for later versions of Outlook. When this happens the mapisvc.inf is created in the windows\system32 directory. The entires in the file are correct but it is in the wrong location. The correct location is dependant on the Outlook version. You must add the entries from the \windows\system32\mapisvc.inf file to the ones found in

“C:\Program Files\Common Files\System\Mapi\1033” –

Different versions of MAPI may be configured in different ways, creating the file mapisvc.inf in a different location.

Thanks Jeff

The entries were already present in the inf file in the C:\Program Files\Common Files\System\Mapi\1033 directory, but I did try merging the two files, (and deleting the duplicate entries) but to no avail.

In fact both of the files are now identical.

Did I need to reboot, surely not.

I di obviously restart the Notes Client and Outlook Client.

Do I need to delete and re-creat the Outlook Profile. I am going to try this now.

It seems to me like it could even be a registry issue.

What is even more annoying is that some machines seem to work fine O-O-T-B

BTW, I have tried using The Notes 6 (& 6.5) Multi User install, (C:\Prog Files and C:\Doc & Settings etc) and the normal all three clients install (installed to C:\Lotus\Notes)

argh.

Just tried to delete and re-add the Outlook Profile. No joy.

OK, well in the end I have gone for this workaround. I have known about this but it is only an option for Office XP (2002) users.

You need to install the Outlook 2002 Connector for IBM Lotus Domino

There is no equivalent for Office 2003, nor Office 97/2000

But it really does work very well. Albeit you need to keep a very trim inbox.

Fortunately we are a reasonable small org so we are ablr to migrate users quickly, but we still have one app that has a dependancy on Excel 97, so can’t take the whole office range up to XP yet.
