We are using windows SBS 2003 and exchange 2003 and client machines using windows XP pro with Outlook 2003. We had some problem with our router and had to replace the router. After connecting the new Netgear the internet and network connection is back on however unable to receive e-mails. We can send outgoing emails without any problem. I have setup the new router to the same configuration as it was before (I mean with same internal IP, Gateway, DNS etc). I have also check with our web hosting company and they did confirm the e-mails are forwarded to our external IP address which is Address Is 126.96.36.199. This IP is provided by our ISP (BT). And the ISP also confirmed that are we currently using the same external ip.
Please find enclosed IP details and also the DNS test report for further info.
