Message: client connection refused

Explanation: The client refused a connection on the port number for bpcd.

This error can occur because of the following:

No process listening activity occurs on the bpcd port
The number of connections to the bpcd port is more than the network subsystem can handle with the listen() call

Recommended Action: Do the following, as appropriate:

For Windows NetBackup servers:
- Make sure the NetBackup client software is installed.
- Verify that the bpcd and bprd port numbers in the %SystemRoot%\system32\drivers\etc\services file on the server matches the setting on the client.
- Verify that the NetBackup Client Service Port number and NetBackup Request Service Port number on the Network tab in the NetBackup Client Properties dialog match the bpcd and bprd settings in the services file. To display this dialog, start the Backup, Archive, and Restore interface on the server and click NetBackup Client Properties on the File menu.
  
  The values on the Network tab are written to the services file when the NetBackup Client service starts.
- Verify that the NetBackup client service is running.
- Use the following command to see if the master server returns correct information for the client:
```
install_path\VERITAS\NetBackup\bin\bpclntcmd -pn
```
On UNIX and Linux servers, do the following:
- Make sure the NetBackup client software is installed.
- Verify that the bpcd port number on the server (either NIS services map or in /etc/services) matches the number in the client's services file.
For a Macintosh or NetWare target client, verify that the server is not trying to connect when a backup or restore is already in progress on the client. These clients can handle only one NetBackup job at a time.
