Hi! I have a big trouble with RPC over HTTP. My network: <Internet> <Netscreen FW1> <ISA 2004> <Netscreen FW2> <Internal Network with FE+BE+GC> In internal network I cann access FE/BE over "RPC over HTTP" without any problem. I have only problem if I want to access from external to internal network over "RPC over HTTP". Other connections, such as OWA, IMAP4, POP3 from external to internal work well. ISA 2004 monitorr tells following: Allowed connection RPC_OUT_DATA https://owa.intra.exchtest.net:443/rpc/rpcproxy.dll?owa.intra.exchtest.net:6004 Failed connection RPC_IN_DATA https://owa.intra.exchtest.net:443/rpc/rpcproxy.dll?owa.intra.exchtest.net:6004 Allowed connection RPC_OUT_DATA https://owa.intra.exchtest.net:443/rpc/rpcproxy.dll?owa.intra.exchtest.net:593 Failed connection RPC_IN_DATA https://owa.intra.exchtest.net:443/rpc/rpcproxy.dll?owa.intra.exchtest.net:593 What does it mean what ISA 2004 in monitoring shows? Why cannot I access over "RPC over HTTP" from external to internal? Please help!!! Outlook client tries to connect, but then it says that "Outlook must be in online mode to connect Exchange". It is online! I can use other services from Exchange without any problem, but not RPC over HTTP! Best Regards Mustafa
