WMI not working on isa server 2004 localhost

am not able to send snmp or wmi requests to the is server 2004 proxy and firewall even when i precise to open all ports to the network management console to the the isa server 2004 local host.
Here is what i am getting in the logs:
Transport      Destination Network      Destination IP      Destination Port      Protocol      Action      Rule      Client IP      Result Code
TCP      Local Host      192.168.1.22      135      RPC (all interfaces)      Initiated Connection      RPC For the Network Management Console      192.168.2.1      0x0
TCP      Local Host      192.168.1.22      135      RPC (all interfaces)      Closed Connection      RPC For the Network Management Console      192.168.2.1      0x80074e24
TCP      Local Host      192.168.1.22      135      RPC (all interfaces)      Initiated Connection      RPC For the Network Management Console      192.168.2.1      0x0
TCP      Local Host      192.168.1.22      135      RPC (all interfaces)      Closed Connection      RPC For the Network Management Console      192.168.2.1      0x80074e24
