Hi all, I am using Exchange 2K (SP3) on Win2k(SP3). Server is connected to rest of the exchange servers with dial-up connection (256 KBPS). There is a high bandwidth utilisation. I am not getting the reason for this. Mails transfer is not that high and we are not hosting any public folder on this server. If I shut down the exchange server the bandwidth utilisation comes to normal. Can anybody please tell me what counters I should examine for tracking the root cause? BTW what components in exchange generate the network traffic( like public folder replication, mail transfer, RU service,??????) Regards, Pranav
