Just recently, a number of our users (Outlook 2003) have been having problems connecting to the exchange server (Exchange 2000). Everything was working fine till yesterday afternoon when several users couldn't send emails.
A good majority of our users can still connect and not have any issues but 6 users just lost connection to the server. We can ping the server but we can't pull nor send any emails. All users are using Dell Dimension 3100 with 512 RAM standard. We are on a branch office and is connected to the exchange server at corporate office with T1 lines. Internet connectivity to the computers with issues have no problems and no changes have been made to the firewalls either.
