AS400 Display and Ip Address

This Morning, I got a call from one of branch office that complain about her display can't sign in.
So I checked it and user always use this display PSPDLN13.
I run WRKCFGSTS CFGTYPE(*DEV) CFGD(PSPDLN13) on AS400 to view it's current status. So this display in use by someone else.

I tried to varied off that display with command number 2. But it won't, that display still back to it's current status Sign On.
I think it's happened because user probably set Auto-reconnect and Bypass signon on his display configuration. Nothing I can do to make that display varied off. But I still know what IP Address use that display.

Here they come how to do it:
1. Type WRKCFGSTS CFGTYPE(*DEV) CFGD(PSPDLN13) and enter
2. Press F14 (Work with devices), if you can't find it (You can't :P). Just pressed SHIFT F2.
3. Type command number 5
4. Walaaah, you can find IP Address in Internet address.
