We are running an exchange 2010 hub server with forefront security 2010. This has been in place for sometime, but suddenly we are unable to load the anti-spam configuration settings under policy management, the loading bar just stays on the screen and eventually generates an error: 'Microsoft Forefront Protection 2010 for Exchange Server is unable to perform the requested function. This may be because microsoft forefront services are unavailable. Ensure that all microsoft forefront services are running and that windows powershell is functional.'
I've checked all services and they are running and I can open powershell. I have restarted all the forefront services with no difference. The only other thing in the console that I can't access is the online protection configure.
Mail still seems to be flowing through and the antispam is still quarantining messages as needed.
