Determe Lotus Single Logon feature installed

Is there a way to remotely determine if Lotus Notes Single Logon is enabled on clients?

We would like to use a vbscript or similar to run in our environment that would report back. However, we are having difficulty pinpointing a single universal method for determining the status of Lotus Notes Single Logon.

We have about 270 Lotus Notes Clients, some are 8.5.3 and most are 8.5.2. We want to make sure that single logon is installed and turned on, but it is difficult to determine at this point. We have majority Windows XP with some Windows 7.

So far I have found that some Windows 7 clients have a separate Lotus Notes Single Logon service installed, other Windows 7 clients with Lotus Single logon enabled and working do not have this service, same for XP clients with either Notes 8.5.3 or 8.5.2. Some Lotus clients have the nslsvice.exe but other clients do not.

Any ideas or assistance is greatly appreciated, I thought I had the key with the service or the .exe, but now I am back to square 1.

Subject: Can’t you use a policy?

Can’t you just use a policy to push that setting out to all clients? Then you don’t have to worry about it.

Note: I am a developer, so I am not sure if that is a setting you can control with policies, but I would assume it is.

Subject: Feature not installed?

Domino policy may work, but what if the feature is not installed in the first place? That is what we are trying to determine without having to touch/contact each user. So we can install, or we may just end up pushing the feature to everyone.

However, if anyone has run into this or scripted something for this situation it would be handy.

Subject: Check Registry

You can write a button or a vb script to report back is there is a registery entry for the service and if it is enabled.
