Name Resolution Problems when Installing the
Windows Cell Manager
During the installation of the Data Protector Cell Manager on Windows,
Data Protector detects and warns you if the DNS or the LMHOSTS file is
not set up as required. In addition, Data Protector notifies you if the
TCP/IP protocol is not installed on your system.
Name resolution fails when using DNS or LMHOSTS
If the name resolution fails, the “error expanding hostname” message
is displayed and the installation is aborted.
• If you encounter resolution problems when using DNS, you get a
warning message about your current DNS configuration.
• If you encounter resolution problems when using LMHOSTS file, you
get a warning message to check your LMHOSTS file configuration.
• If you have not configured either DNS or LMHOSTS, you get a
warning message to enable the DNS or the LMHOSTS resolution in
the TCP/IP properties dialog.
Action Check your DNS or LMHOSTS file configuration or activate it. Refer to
“Hostname Resolution Problems” on page 565.
The TCP/IP protocol is not installed and configured on your
system
If the TCP/IP protocol is not installed and configured on your system, the
installation is aborted.
Data Protector uses the TCP/IP protocol for network communications; it
must be installed and configured on every client in the cell.
Action Check the TCP/IP setup. For detailed steps, refer to the online Help
index keyword “checking, TCP/IP setup”.
