NetWorker Module for Microsoft Applications version 2.4.0.388 and Its SQL sERVER

First you can use nsrpots to verify whether it shows:

Service ports: 7937-9936

if not, best to change the port range to 7937-9936.

And use "netstat -aon" and the "services" tab of Windows Task Manager to check whether non-networker applications are using the ports in 7937-9936.

In addition, sometimes timeout problem may occur between NetWorker server and NetWorker client. This can cause large save set backup failure.

We should tune the TCP/IP keepalivetime.

To tune the TCP settings, set TCP Keepalive to prevent connection timeouts:

1. Run regedt32.
2. Make a backup of the following registry key. For example, right-click Parameters and select the Export menu option:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. If the KeepAliveTime parameter is not already present in the following location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
a. Right-click in the Parameters List window.
b. Select New>DWORD Value.
c. Name the value KeepAliveTime.
4. Double click the KeepAliveTime entry:
a. Type 3420000 in the Value Data field.
Note: If the TCP timeout on your firewall is less than 60 minutes, this value will need to be adjusted lower
b. Click Decimal in the Base section.
c. Click Ok to save the changes.
Note: The registry key named KeepAliveTime is case sensitive.
5. Reboot to apply the changes.
