Well-known security identifiers in Windows operating systems

If you ever poke around the registry like I do from time to time and wondered what all those SID's are under HKEY_USERS, then this KB article will be useful: Well-known security identifiers in Windows operating systems

I've been using the PeerCollabRegisterApplication API to register applications. When the registration type is PEER_APPLICATION_CURRENT_USER it makes sense. However, when the registration type is PEER_APPLICATION_ALL_USERS, I see an odd behavior. Under User1 account, I register Notepad for All Users. When I login to User2 account and enumerate what's registered for All Users, I would expect to see Notepad, however, I don't.

I'm using the February CTP of Windows Vista. Any comments is appreciated.

So in my first article about the new peer-to-peer collaboration features in Windows Vista, I came across something interesting.

After registering for events, I successfully get notifications when a user account on the subnet signs into People Near Me.

I noticed that when the screen saver kicks in, collaboration applications receieve a DELETED event. I suppose this makes sense, since the screen saver is set to force the user to re-login.

I also noticed that when remote user accounts that are signed-in, log out, there is no DELETED event. I think this might be a bug. I'm only testing with multiple virtual machines on one computer, but the behavior is inconsistent with what I'd expect.

Writing Article Again and MVP

After a couple of months break, I'm finally back to writing peer-to-peer articles. Expect the next one in a couple of days.

During this break, I was awarded a Microsoft MVP for Windows Networking. Besides recognition of my contribution to the public domain, it comes with some goodies, including a much needed MSDN media set.

Tripp / Ravi, if you had anything to do with this, a BIG thanks to you.
