    ISA Failing it Connect To RPC Service

    Hiya,

    After the nice a full system shutdown over the hols, I am now having a problem whereas the ISA server is failing to connect to the RPC Server on my DC, which i think is problems with OWA on exchange 07 (isa is denying connections, its not the exchange server as it works internally), the isa is not used to proxy, is just there as a firewall, we have a squid proxy installed for all internet traffic. nothing changed with the isa, but its not allowing the connection

    I have got this error from the isa logging, but i have set the connectivity verifier's with the dc's to use RPC on port 135 like this is failing on, which is saying the connection is working.
    Failed Connection Attempt WLD-SVR-016 05/01/2010 14:06:37
    Log type: Firewall service
    Status:
