Renewing IP address lease

[Azar]

Most of our win2k and winxp computers are DHCP enabled .
However we can only manually renew IP address's, as soon
as the computers are restarted or shutdown and rebooted
they lose thier IP address and are not able to connect to
the DHCP server.
Does anyone know how to solve this problem ?

After you restart your client computers, do they have an address in the
range 169.254.y.z? If so then they are using APIPA to auto-assign themselves
an IP address because they can't contact a DHCP server, in which case you
either have a problem with your DHCP server or with your network.

If the answer to the above is no, what is displayed when you type ipconfig
/all on your client computer after restarting?

First thanks for your reply,
After I start the client computer it hangs for a long time
and then boots to the local machine with the ip address,
subnet mask and Default gatway of either 0.0.0.0. or
169.x.y.z address. The strange thing is that it does not
happen to all the machines.I have some of the machines
that are also dhcp enabled and are not experiencing this
problem at all.

To add to Mitch's suggestion, this could also be a connectivity issue or it
could be due to the use of multiple protocols and a binding order issue. I
had problems with this, in the past, and it was always connectivity, usually
physical, and always with new computers and drops, patch cables, punchdown
issues, i.e. wrong strand, bad connections, etc.
