HP Laptop dv7 w/ Windows 7 Pro x64
has bluetooth/wireless/ and wired network port.
So here is the situation. I work in a Office at "point A" and inside "Point A" i plug my network cable into my laptop / computer. Everynow and then myself or a co-worker will unplug that network cable before shutting down (while it's on the desktop) then we shut down the pc and go home.
The next day we take our laptop to the Office in a different building "Point B". Now when you plug into that office you can't connect to the network and /release / renew or the troubleshooter cannot connect the computer to the network at that office. You have no inTRAnet or inTERnet.
INTERNAL Network info:
172.21.2.1 - 172.21.3.255
172.21.62.1 - 172.21.62.255
so anyway when i take this LAPTOP to office B, when i do ipconfig i get a IP Address for Office A and a subnet mask of 255:255:255:0, and a Gateway of 0.0.0.0
I've tried /release /renew in both admin mode / regular. In safemode with networking.. and nothing. The only thing that works is to give it a static IP address with a proper DNS and using a empty IP address i get from a network scanner (to make sure i'm not using a IP address in use)
How can i reset this network so that it pulls from the DHCP router correctly.
Oh not to mention when i go BACK to "point A" and plug in everything comes back as if nothing has happened.
