  • Server running slow BPA says too many RPC calls.

    So I run perf mon and I am seeing that I have active connections of about 1250 and I only have about 48 users. Plus about 20-30 smartphones. How can I see what account is making all these connections? Or why? Thanks in advance.

    Assuming that the RPC calls are from Exchange clients, you can install and run the EXBPA to find the user(s).

      THanks for the quick reply. That is the thing I cannot figure out where to look to find out who the users are and the connections that are being made. I have EXBPA it's how i found out about the RPC being too high. supposed ot be .25 I am at 5.75

      Let me add to this I ran the get-logonstatistics and it's showing about 150 connections but when I add the active client logons in my perf mon it is now shoing about 600. What is the discrepency?

        One of the tests in the EXBPA should identify the source(s) of the high RPC calls.

          Any help you can offer as to what test?

            Sorry, it's the EXTRA I was referring to, not the EXBPA. You can download the EXTRA and install it. It has a performance troubleshooter that has specific RPC tests.

                Thanks, it appears that Exchange 2007 has EXTRA in it already I ran those tools but it just says that i have too many RPC connections not who is the culprit and at the end the suggestion take me to MS site that says to either find out why so many connections or to offload users to another server. I mean really 50 users is too many for one server LOL (4gb, quad core xeon 3ghz, SAS raid. Server is only a year old. So I decided Iwill show you and I ordered 16gb of ram for the servers. That was the other suggestion on MS site.

                  Oops sorry, was just linking, didn't read the thread

                  You could try Wireshark?

                  Maybe something here too?
