SSRS 2008 lost ReportServer Users

Hi,
we have installed SSRS 2008.
In the dbo.users (from the ReportServer Database), are 501 records.
But if i open the web gui from the ReportServer web
i can only see about 100 users, where are the other ones?

2 Days ago everything was ok, in the meantime nothing has changed.
whats wrong? Any Idea?


Thanks a lot for any help!

Hican you check whether the users have been removed from the ReportServer
