brian..thanks for the help..
.but the message is still there..everytime a user logins into his account , a warning dialog box says "Your server's license has expired" .
I'm on open Suse 9.3 (not on MAC , as in the bug you told me about) and also i'm not getting any other message (in the admin console) except this one . In fact , as i mentioned before , everything is working fine except this thing .(and this is what's driving me crazy

)
i'm thinking very seriously of making a fresh install .. is there a way to quickly save all the accounts , domains and distribution lists i'm having now (on a cd/dvd maybe) and then just restore them in the new installed server.. ?
