You can use the Delete Windows Server (DLTWNTSVR) command to uninstall Windows server from an Integrated xSeries Server. Prior to running the Delete Windows Server command, shut down your integrated Windows server from i5/OS. See Start and stop an integrated server.
The Delete Windows Server (DLTWNTSVR) command deletes the specified Windows network server description and associated objects that were created by the Install Windows server (INSWNTSVR) command. These objects include the network server description, line descriptions, TCP/IP interfaces, and system created network server storage spaces. The network server must be varied offline before this command is issued.
If the DLTWNTSVR command cannot be used (for example if the server's NWSD object no longer exists but some of the associated objects need to be cleaned up) you can manually delete the server and the associated objects using the following procedure:
If you remove all your Windows and Linux® servers that use a particular network server host adapter (NWSH) object from i5/OS and plan not to install any more servers that use the NWSH, you can delete the NWSH. See Delete a network server host adapter.
If you remove all your Windows and Linux servers from i5/OS and plan not to install any more, you can delete IBM iSeries Integrated Server Support to free up the storage the product uses. See Delete the IBM i5/OS Integrated Server Support, i5/OS option 29 (5722–SS1).
