Hello We're running Exchange 2007 SP2 on Windows 2008, along with Outlook 2007 SP2 clients. Exchange servers are all based in UK. One of our offices is based in Germany and sometimes the WAN link is not great. This means that when they access Outlook it can be slow due to latency between the servers (UK) and client. When they call up saying there are 'Exchange issues' is there a tool we can run to show that network latency is causing the problem? I've heard of RPCPing, but not sure how this would work in the environment. Any help appreciated!

pathping - the easiest and built into windows rpcping would also work in your enviroment the best thing would be to collect data when it works fine, and when they are complaing and compare them With kind regards Krystian Zieja http://www.projectnenvision.com Follow me on twitter My Blog

Hi Krystian Thanks for the reply. I've been reading about rpcping here: http://support.microsoft.com/kb/831051 To confirm, can we run this from the server side to verify the latency between the Exchange server and Outlook client? And what sort of latency would this be; network, RPC, or both? Secondly, if the client was: User mbx: User1@domain.com Account: Domain\User1 IP: 192.168.1.1 Client hostname: Machine1.domain.com What command would I actually run from the server for rpcping to work?

Hi Joe, I want to verify some information: Does the clients which in the office of the Germany use outlook anywhere to connect the exchange server. If so we could use rpcping to check it. In my opinion, if the network not stability, we do not need to use the rpcping, we could use pathping/ping to check the whether the data packet is lost every period. Such as blow: on the client box, run cmd Ping exchangeservername Pathping -n exchangeservername rpcping -s exchangeserver name You could follow the DOC to make some tests. http://technet.microsoft.com/en-us/library/cc958876.aspx http://support.microsoft.com/kb/831051 Regards!
