Hello all,

So i have been monitoring my Exchange server because i have been noting minor perfomance problems. Using the Exchange Performance monitoring tool and ExMon, i was able to identify users taht were making an unusually large amount of RPC calls (7 - 14 times that of a normal user). Not only were these users exhibiting heavy RPC usage, it also appeared to be constant. Minute to minute the same users would remain at the top of the list sometimes account for 80% of all the RPC traffic in any given minute.

So i did some investigating. After some detective work i found what appeared to be the problem. They all had goole desktop installed. So i removed google desktop from one of the users. The user immediately dropped off my list. I installed google desktop on my workstation - and guess what - i immediately jumped to the top of the list for RPC connections.

This is a good way to make email admins ban the application from end user workstations. Perhaps you may wish to investigate. I believe i did solve the problem by runnign the user in Exchange Cached mode, but regardless, many admins are quick to ban an application because that is often the easiest way to remove the trouble caused by it.

Thanks,
