TMG - problem with server that is unable to update the configuration

I use Windows server 2008 EBS and all servers are virtual and instaled on ESXi host. Forefront is instaled on secure server. On basic configuration the firewall in runing but the CSS and adam are not in sync. Even on a small change in rules the firewall goes in lockdown mode. Even if a start the service in firewall goes in lockdown mode in 5 minutes. When i change the rule to basic settings the firewall start to work ok. I rapair CSS and now the CSS and ADAM are in sync but again when i change even a letter in a firewall rule, firewall goes in lockdown mode in the moitoring the configuration is unable to update in is not in sync any more. And now if a restart the server the configuration is also unable to update and is not in sync. Also it show that the last time he was synced in 19.12.1999 ?????
I am working on this problem for weeks and i cant find the solution. Is there a problem with CSS or ADAM?
I would apritiate any help!
Thanks!
