I would start checking if the DHCP Client service is running.
I would also try and get the latest drivers for the NIC.
is it a fresh windows 7 install ?

Browse All TopicsHi everybody
I have a strange situation here.
On our Network is one W2K3-DHCP Server working.
Newly installed XP Clients get IP-Adrresses and options BUT - Vista and Windows7-Clients not.
We turned off the Firewall for Testing Purposes.
If we manually configure the correct Gateway (only one Subnet) the Win7-Client will catch a correct IP while running. Then i boot the Client, and have again an APIPA-Adrress.
In that Network is also a Cisco-Device that play a DHCP-role (different Subnet) for IP-Telefon.
We have tested Client directly attached and behind a IP-Telefon, no Difference.
Im a bit confused
Has any body a idea
Thanks and greetings

- No the cisco-device is on the same phys. network, because the W2K3-Server can't serve the IP-Phones.
W2K3 send the same ip to each phone.
- Even XP-maschines fresh out of the box have no problems.
- I have checked this before - no errors, but i will check once.

3 x Yes
and it won't work with my Vista-Notebook. In other Windows-Networks i have no Problem with DHCP on my Notebook.
sorry, must leave now - so till tomorrow
greetings
if the cisco is a dhcp server on the same network then you have a problem - when a pc issues a dhcp request - it is a broadcast and then works with whichever system responds to that broadcast - hence you can only have one dhcp server on a network.
if you need to use the same network but a different subnet then you need to setup a vlan on your switches,
or you need to configure dhcp to look at the ma addresses of the request and assign Ip appropriately.
my guess - if you turn the cisco off, and restart the dhcp service on the 2003 server - then your win7/vista machines will work.
hi to all
thanks a lot for the answers and sorry for the delay.
i'm on another location with plenty of work.
I also think that the cisco (DHCP is on another vlan) is a problematik piece.
i will check this out with the external partner on thuesday,
and then i will post also parts of Logs, if the problem still exist.
i wonder why 100 XP-Clients and IP-Phones work less problems... hmm
thanks again
greetings

is the cisco on a physically different subnet - you can only have one dhcp server on a subnet
are the xp machines just remembering their IP - have you done a full ipconfig /renew on the xp machines
are there any event log errors on either the server of the win7/vista systems?
