I am running MS Windows Server 2003 as a domain controller, and it also acts as my DNS and DHCP server. STarting last week several users have noticed delays on the network in the form of Outlook losing conenction to Excahnge and reconnecting in 10 - 20 seconds, slow network printing, telnet sesions to the AS400 disconnecting, etc... The server was way behind on patches so I downloaded and installed what was needed on Sunday and the delays were first reported on Wednesday. I don't see anything out of the ordinary in the event viewer and the network connection appears normal (100mb, full duplex). Could there be something happening on my domain controller to cause intermittent delays on the network? It seems to affect different people at different times.
