Windows NT Clients

On Backup clients for Windows NT, you must manually update and verify the following files:

• The %SYSTEMROOT%\SYSTEM32\DRIVERS\ETC\HOSTS file must contain the Internet address of the Backup client and the Backup server, unless you are using DNS or Windows Internet Naming Service (WINS). The HOSTS file is a simple ASCII text file with one line for each Internet Protocol (IP) address. The IP address is the first entry on the line followed by the hostname and all aliases for each machine. For example:

  127.0.0.1 localhost loopback 137.69.8.1 server server.companyname.com 137.69.8.2 client client.companyname.com

  Your %SYSTEMROOT%\SYSTEM32\DRIVERS\ETC directory should contain a sample HOSTS file that gives details about adding entries to the HOSTS file. Do not delete or comment out the entry for localhost loopback.

  If you are using DNS or WINS, verify that the DNS or WINS server has entries for both the Backup client and the Backup server.

• The SERVERS file is typically in C:\WIN32APP\NSR\RES. Backup uses the contents of this file to control who has the right to request a program to be executed on this client.

  If you want this client to back up to other Backup servers, you must add the names of the additional Backup servers to this file. One server name per line.

  If you want other clients to be able to perform directed recovers to this client, you will need to add their names to the \nsr\res\servers file. One client name per line.

  If you want to allow any Backup server to back up this Backup client, delete the SERVERS file.

  After you save your changes, you must restart the Backup Remote Exec Service to make your changes take effect.

  To allow any Backup server to back up this Backup client, delete the SERVERS file.

• The Backup client for Windows NT must have the latest service pack from Microsoft applied.

• Make sure that the following services are running:

  • Backup Remote Exec Service (nsrexecd.exe)

  • Backup Portmapper Service (also known as portmap.exe)

    Backup Portmapper Service is an optional service for Backup clients. To enable this service, start it before Backup Remote Exec Service.
