Forefront TMG client showing ? in session monitor

I have deployed the Forefront TMG clients to the majority of my client PCs, but I notice in the session monitor that all of the client usernames have (?) after them. Is this normal?  If not, what action is recommended?

Also, there are still some 'anonymous' entries under Client username, even though the same IP has other connections that list the username properly.

It feels like I missed a step?

these sessions do not require authentication, so no user name is required for them. thats why users appear as "anonymous"

That's what I was looking for - thanks!

Unfortunately we cannot require authentication because part of Internal network is public wireless; I will ignore this  issue for now.
To make it clear, it depends on the allow rule if it require authentication or not (all users).

If not require, anonymous users will appear.
If it require and ISA client used, then a "?" mark will appear at the end.
you are welcome...
