You can test whether your connection method to iSeries NetServer™ (for example, DNS) is up and running if you experience connection problems. To do so, follow these steps:
ping QSYSTEM1
If you get a positive return value, then the client connection to iSeries NetServer is operating normally. This means that the method the client uses to connect to iSeries NetServer and iSeries is up and running.
Tip:
Run nbtstat -A ip-address-of-server from a command prompt on the client to check connectivity: C:\WINDOWS>nbtstat -a qnetserver. Using nbtstat can also be helpful with connectivity information in case the name of the server is unknown or cannot be resolved.
Another way to check client connectivity to iSeries is to see if there is an active NetServer session for the client. Using iSeries Navigator under Network > Servers > TCP/IP, double-click iSeries NetServer and then click Sessions. A listing of users and their respective workstation name, logon type, and server session is displayed.
