Hi Exchange Experts Have been reading about a tool named RPCPing here: http://support.microsoft.com/kb/831051 Unfortunately, the article isn't that clear :( I had some questions on it: 1. Can this be used to troubleshoot connectivity issues between Outlook clients and Exchange servers, particularly where the Outlook client is in a differnt site across the WAN 2. What's the actual difference between running RPCPing and just normal Ping? What does RPCPing actually measure? 3. Let me give an example where: Client details: User mbx: User1@domain.com Account: Domain\User1 IP: 192.168.10.100 Client hostname: Machine1.domain.com Server details: Servername: Exch1.domain.com IP address: 192.168.1.1 I have the Server Resource kit tools installed on the Exch server, but nothing special installed on the client. The client is saying that Outlook is slow and I want to show that a poor network connection maybe causing this. What command would I need to run on the server, using RPCPing, to show this?

Hi, RPCPing utility can be used to check if the Microsoft Exchange Server services are responding to RPC requests from the client workstations via the network. Ping is used to check the network connection between two machines. You should copy RPCPing to your Outlook Client, and start with checking/pinging the RPCProxy. For detail command, you can refer to the article. Regarding to the Outlook performance issue, I would like to confirm when Outlook is slow. Does the issue occur when trying to launch Outlook or send an email? Also, does the issue occur on certain machine or each machine. Please launch Outlook in Online Mode to check whether the performance can be quicker. Thanks.

Hi Novak I have read the article (in fact I refer to it in my original post :) ), but I find it confusing. Say in an example situation where an Outlook client connected to Exchange over the network (note, *not* the Internet) is experiencing problems with slowness etc. Will RPCPing help diagnose problems, what can I actually get out of it if I ran RPCPing command from the server to the client? Would it be the RPC Latency for that particular client? If so, couldn't I see this info from get-logonstatistics for that mailbox? Secondly, do you know the answer to this question: Let me give an example where: Client details: User mbx: User1@domain.com Account: Domain\User1 IP: 192.168.10.100 Client hostname: Machine1.domain.com Server details: Servername: Exch1.domain.com IP address: 192.168.1.1 I have the Server Resource kit tools installed on the Exch server, but nothing special installed on the client. The client is saying that Outlook is slow and I want to show that a poor network connection maybe causing this. What exact command would I need to run on the server, using RPCPing, to show this?

RPCPing does not help to troubleshoot this kind of problem. It just checks the connection status between Exchange server and Outlook client from Default Ports. First, I would like to confirm whether the issue occurs on certain client user or each client user. If the issue occurs on certain user, I suggest you perform the following steps to troubleshoot the issue. 1. Launch Outlook via Online Mode instead of Cached Mode for a test. 2. Create a new Outlook profile. 3. Perform a Clean Boot to check the result. If the issue persists on each client, I suggest you run Performance Counter on Exchange server and post the result. Thanks.
