We had our ADSL connection accidentally inactivated by our ISP. During that time we were forced to go back to using a Dial-up account. At the time, our ADSL router was performing Port-Redirection for our mail server, OWA and pop3. When we transferred to dial-up, email delivery stopped. We run the Secure Mail Server wizard within ISA Server which is installed on our server which also runs Exchange 2000 for our mail server. This fixed the problem with mail delivery. But... We are now back up again on ADSL and although our Router (DLINK DSL-500) says we are connected, neither the server or clients can browse the internet or send and receive email. I have checked DHCP is assigning the IP address of the router as the default gateway. we can ping the router, ping the server etc from the clients but cannot do anything else.. Please someone help. I have tried all i can think of.. Please email me with any suggestions... Regards, Belinda
