Troubleshooting Tips

The following answer common questions that arise when managing your equipment. For more
details, refer to the User Guide. The applicability of the following will depend on what drivers and
other add-ons you have installed with OpenManage Network Manager.
The following sections discuss some troubleshooting techniques. See this software's User Guide for
more.

Name Resolution

If your network does not have DNS, you can also assign hostnames on a Windows platform n the
file %windir%\system32\drivers\etc\hosts. Here, you must assign a hostname in
addition to an IP address in the system. Here are some example hosts file contents (including two
commented lines where you would have to remove the # sign to make them effective):
# 102.54.94.97
# 38.25.63.10
127.0.0.1
This software supports installation to only the local file system. Avoid installing to shared drives.
