We had a router/modem outage over the weekend. I replaced this and changed the IP address to be same as the old modem plus I logged in with the same ADSL username password and checked that my external IP is correct. I can browse the Internet and send e-mail but I can't receive e-mail or OWA/RWW (I have an external domain name that resolves to the IP address).
I have restarted the server but this hasn't helped. I also ran the Internet connection wizard twice but this failed for some reason....I am afraid I did not take note of why at the time.
Any ideas based on the info I have given?
