My server is running ISA 2006 version 5.0.5720.100 on Windows 2003 standard , begin this week I noticed that is is no longer possible to access the Firewall Policy rules in the ISA management console, instead I receive a error message:
"A failure occured the task was not activated" error code is: 0xc0040305
details of the errormessage: (where 'INBOUND ...." is the name of the rule and "konsrv4" is the servername
The string is empty or invalid.
"The error occurred on object 'INBOUND --> LAN KonSRV1 (Webmail)' of class 'Policy Rule' in the scope of array 'konsrv4'."
It appears that there is a invalid value in the object of that specific rule and now I'm not able to change or export my firewall policy rules. I also fear that when I reboot the machine or ISA service it might not come online again.
Any idea's how I can resolve this problem ?
