The information in this article applies to:
- Microsoft Exchange Macintosh client, versions 4.0 and 5.0
SYMPTOMS
If MacTCP is not configured correctly, an error is displayed when you
try to check a name using a TCP/IP connection type.
The following errors will be generated:
The name could not be resolved. Network problems are preventing
connection to the Microsoft Exchange Server computer. Contact your
system administrator if this condition persists.
The name could not be resolved. The action could not be completed.
WORKAROUND
- Verify the account name using the Microsoft Exchange Administrator
program.
- From the Mac workstation, make sure the Microsoft Exchange Server and
name are entered correctly. Do not use the Appletalk name if it's
different than the Microsoft Exchange Server name.
NOTE: Appletalk name is setup through MacFile control panel on the
Windows NT Server.
- Make sure MacTCP Ping can successfully ping the Microsoft Exchange
server. If not, MacTCP is not correctly set up on the workstation or
TCP/IP is not correctly set up on the Microsoft Exchange Server
computer.
- If Appletalk routing is enabled, try checking the Appletalk
Connection option instead of TCP/IP. If the name can be resolved,
then the problem is a MacTCP or DNS (hosts) issue.
- If MacTCP is using DNS, make sure MacTCP has the correct IP addresses
in the DNS configuration. Make sure a default DNS has been selected.
Also, verify that the DNS has the correct name resolution entered for
the Microsoft Exchange Server (appropriate A and MX records.).
- If a local Mac hosts file is used, a CNAME and A record must be entered.
"Hosts" file is located in the "System folder" by default (and should be
located in the System sub-directory to use with MacTCP).
Mac hosts file format:
<Exchange server name> CNAME <IP domain name>
<IP domain name> A <corresponding IP address>
For Example:
EXCH1 CNAME exch1.business.com.
exch1.business.com. A 157.54.16.157
NOTE: If you are using "Open Transport" and TCP/IP, you need to...
* Create hosts files. (Use example above.)
* Go to Apple (menu), Control Panels, TCP/IP
* Go to Edit (menu), User Mode. Select "Advanced", and click OK.
* Click on "select hosts file", and highlight the hosts file already
created, click Open.
* Close the TCP/IP control Panel, and click "Save" when prompted.
* Restart the machine.
MORE INFORMATION
- Microsoft Exchange uses name resolution to check the name.
- It is recommended to use the DNS setup instead of a local Hosts file
for ease of administration, setup, and troubleshooting.
