For an added measure of security, you can hide iSeries™ NetServer™ from the Windows® My Network Places.
To hide iSeries NetServer from the network, follow these steps:
Setting the browsing announcement interval to None stops the host announcements to the network. It also stops domain announcements if iSeries NetServer is configured as a logon server and might cause problems for logon services for some networks. In general, the default browsing announcement interval should be kept if iSeries NetServer is a logon server. The default browsing announcement interval is 720 seconds, or 12 minutes.
