Release and Renew IP Address

[Vince]

I'm trying to release and renew a IP address with the DHCP
server but I keep getting the same IP address. I'm using
the ipconfig /release from the command line.

DHCP servers typically don't hand out a "random" address,
they hand out the next address in their pool. If you
release, they have your old IP available in the pool, and
it's available when you ask for a lease. If nobody else
requests an IP between that time and when you ask for one,
there's a good chance you'll get back the same IP address.

My computer was connected via cable at home then it was
brought to work and connected to the office network. When
connected to the network at work via DHCP it doesn't
receive a IP address from the DHCP server at work.

All right, that's a different matter.
So you run ipconfig /release.
Do you get any errors?
After you run the /release, if you run "ipconfig" alone,
what IP address does it report?

It should show 0.0.0.0
After that, if you hit "ipconfig /renew", do you get any
errors?
If not, then run "ipconfig", it shows the IP it had from
the cable ISP?
