We have TMG Essential Business Server. The TMG management console fails to open:
Refresh Fail Error. Error 0x8009005, Bad Data.
We are not running VPN so this solution does not apply http://support.microsoft.com/kb/2006046?wa=wsignin1.0 (There is no VPN heading in ADSIEdit console)
Has anyone found a solution this apart from re-installing see http://social.technet.microsoft.com/Forums/en-US/Forefrontedgesetup/thread/d6696c0d-d279-4723-8d1b-a09259a53b2f.
The problem occured shortly after adding some firewall changes.
Is it possible to edit firewall policy settings from the console to see if it will clear the error ?
