NET VIEW IN CMD PROMPT Lists Server name and another not wanted.

Hi i am new to seven forums today and must say i rate it good and useful and helpful advice given.

hope someone can help with me this as i have tried hard myself for a while and read up on it and googled as much as i can find without success.

I have windows 7 ultimate and a wireless router zxel with single areil that i have now removed and disconnected the wi fi in services.msc,i am connected via ethernet cable only now for internet connection.
Reason being is that a while back i noticed in under network sharing centre another PC listed being my neighbours PC LAPTOP with his name next to it i was under public network?,it was not before? i changed it to home network,they live in front of me and have no land line phone or internet and are using a wifi grabber box outside their property to hack other peoples wifi signasl my other neighbour detected it also on his pc,i changed my router that i had another and obviously a new wep key number and put it into WEP2K MODE SECURITY and password protected it,and added the MAC address of my PC.

So this is what happened back in february i finished with my girlfriend!.. not good but before that i had bought her a samsung tablet and of course it being wifi enabled i gave her the wep key number to enter so she could use the internet everyone happy.

In net view i get under server name(which is my pc name but am also now detecting her NAME she used SEREN.......7. in my NET VIEW page in cmd prompt!

How do i get rid of her name in net view?,i am concerned that my security might be breached as her sister lives opposite and her son is pc wizz hacker and i am sure he got my router wep number off the tablet to use just finally under net view there are 2 columns (server name) and next to it( remarks) her name is under (remarks) need some help here guys please.

Sorry for the long drawn out post

If you are genuinely concerned about this then simply adopt a new, strong network key. WEP is the weakest of the security protocols so if your router supports WPA then I would also suggest using that instead.

Why use net view? It's what is showing as connected under Network in Windows Explorer that matters. I just tested net view by turning off the two other computers on the LAN here and then running the net view command. Both continued to be listed, along with my NAS - the only remaining connected device, though the other two did disappear after a reboot.

I have changed the settings already to WPA sorry i quoted incorrectly WEP2K oops!..in router the settings from WEP as mentioned in my post?..the new network key is with the new router yes label under router.
So ineed not worry to see my ex tablet p/w user name am a bit confused on that?,or is it her pc name listed net view.

Any way as you said quote:It's what is showing as connected under Network in Windows Explorer that matters,yes that's just me,as i posted my neighbours pc was shown as connected but not anymore.

Thanks.

Sorry, I missed the bit about the new router TBH I'm not too sure exactly what NET VIEW is reporting, I just know it can report something as being connected even after it is disconnected. Maybe it's reading leases from the router as these will show as still connected until the lease expires.

Thanks for the reply back!,yes i REMOVED the old router and put in another with new network key and change security setting to stronger WPA as previously it was WEP,i think i understand you explanation regards net view,i ddi try to learn all about cmd prompt ect like ipconfig ect ect.

Cheers.:)
