9.4.3 Configuring a DNS Server
A Domain Name Service Server is not required for the messaging systems, but may be a highly desirable way to
centralize the mapping of names to IP addresses. This section briefly describes the setup of DNS server used in this type
of configuration.
To configure a DNS Server:
1. From the Start menu of the PC running Microsoft Exchange Server, select Programs > Administrative Tools >
DNS. If DNS is not available, DNS needs to be installed from the Operating System CD.
2. Check that there is an entry within the domain for each messaging hosts involved.
3. Configure each PC to use the DNS server to resolve names. This is done in the Internet protocol (TCP/IP Properties
form of each LAN interface).
9.4.4 Verification and Troubleshooting
The configuration can be tested by creating a message and forwarding it to the far end of the system. Check that the
message is received at the correct destination. If the test fails, one of the following procedures may isolate the problem.
Ping Test
Make sure that you can ping all end points. If DNS is used, ping using the machine name.
SMTP Service Test and Name Determination
Test that the SMTP service of a messaging system is working by using telnet command as follows.
1. From a DOS or UNIX prompt, type telnet ip-address 25.
2. At the response, type Helo.
3. At the response, type Quit.
4. If the response is not as shown below, then the SMTP service is not running on the machine and incoming VPNM
messages will not be processed. Check that the required PC services are running.
