I have configured SMTP and POP3 in Windows server 2003. Iam able to send mails via SMTP to Outlook client, but not able to receive email to the destination (another server). Same setup previously(just 1 week before) was working fine. but suddenly not sure what settings have changed. Please help me which options to check in 2003.

telnet the server from the client and check it port 100 is opened and also please disable the FW/AV on the server and restart the pop3 service

It is Firewall/Antivirus. Those programs may block the unwanted port access. So you need to check both to make sure that the required port is allowed by those application.

Thanks for the clarification. I would agree that FW/AV is blocking. but we are in a separate LAN and i send or receive within my LAN. That is from my device i send email to the Server and the server in turn should return that email to the device.
While sending we use SMTP and receiving we use POP3, after a Poll interval the device should poll the server for any job it can receive .

As Syed mention, check the POP3 services is running and also check the port 110 is opened.
Make use of SMTPDiag tool. It helps you to troubleshooting the DNS resolution issues.
For more Information:
You can also check it in IIS forum for SMTP and POP3.
