How do you get a change in the users real name to propogate to various places in the network?

In setting up users, I didn't have last names for everyone in the wizard where it asked first and last name (all users will use first name as the login / sbs username).  

Now I am entering the last name on the general tab of each user.  But when they log into xp machines, the name at the top of 2 line login still only has first name (they already logged in before I added last name).

worse, when you look at the global address list, it still only has first names.  is there a way to force this change in user information?  

What if there was a typo in user's info... changing it in general wouldn't  propgate to the global address list?  seems like it should.

I found a properties page in x400 info on exchange page of user properties.  but that still didn't do it

These changes will take up to 48 hours to propagate in your network.  It's handled by the Exchange recipient update service.  So, give it a bit of time and you'll see the cahnges.

Users should log off and back on to their workstations to see the change on their Start Menu.

I am too impatient to wait 48 hours (next change I get, I will test it with the info at the link you offered).

I think I just scoured all the tabs and submenus, found a couple more fields that I changed and the changes were reflected immediately.
