[Serusers] Windows Messenger 5.0

[dhiraj.2.bhuyan at bt.com]

I tried using MSN 5.0 earlier. And I faced exactly the same problem. After sniffing the network traffic I came to know that -

When UserA sends a SUBSCRIBE message to UserB, if UserB has UserA in its list, it sends back a OK message. However it is not smart enough to update the status of UserA (to online) on its own list. It just waits for its turn to send the SUBSCRIBE message to UserA and then only if it gets an OK response back from UserA will it update the status of UserA on its list. So if you let UserA and UserB to be both online for a certain duration of time ( == time between two SUBSCRIBE attempts atleast), you will see the correct status. Another stupid MS implememtation.

That is probably because of the instant messaging and presence model
implemented in MS Messenger.

When you UserA signs in, his messenger sends a SUBSCRIBE to UserB to
find out his status (online/offline). Because UserB didn't sign in yet,
the SUBSCRIBE message will be not replied and UserA thinks that UserB is
offline.

Messenger of UserA tries to resend the SUBSCRIBE again later, but
meanwhile you see UserB offline (even if he signs in during this
period).

After some time (I don't know how long) messenger of UserA should retry
and then you will see UserB online.
