Dear all ,,
there is a Strange issue that i want to discuss ,, we have Core-Siwtch 4503 in the main building which is connected to another Core 4503-E in another building ,, now our PCs connected to the 4503-E ,,, any XP M/C can pick an Dhcp-ip but and M/C run Win.7 Cannot !!!!!!!
action taken :
1st we try to connect our win 7 pc in the node which was connected to xp M/C ,, and it didnot take ip from the DHCP . ,, 2
2nd we ensure from the core-switch configuration and its normal with no mistake
3rd trying to use tool from Microsoft Fix-it Center whih name is ( Microsoftfixit 50475 ) which is just .msi file but the problem face us is that this tool donnot accept to run on win 7 cause its made for vista .
4th after some researchs we notic that there is some modifications have to be performed on registery by disabling the dhcp broadcast flag we did it but nothing change yet
5th now we are waiting to perform another action which is Disable the IP Helper service in win 7
Best regards

Are you using the 4503 as the DHCP server?
Can you post the DHCP server configuration you're using if you are?
Cheers.

yes am using 4503 as the DHCP and i ll post the configuration to you tomorrow

Well, your configuration shows you avoiding the most usual problem with configuring a DHCP server on a Cisco device and Windows 7/Vista - if you add a subnet mask in your "default router" statement it almost alwaysd breaks - but you don't have that in your configuration, so we can rule that out.
Are you 100% certain that your attempt to disable the broadcast flag on the Windows 7 boxes worked? This blog post has a great deal of detail which may help.
If that doesn't help then I'm scratching my head. I just had a look at the DHCP configured on my router, which works fine for both XP and Windows 7 (32 & 64 bit) and I can't see much different from yours (apart from the obvious address ranges etc).
Sorry I can't offer more.
Cheers.

Ok there are [potentially] two issues (one MUCH easier to solve than the other) - let's start with the easy one:
What ever port your Win7 box is plugged into, do this:
ADD:
switcport access vlan xxx
REMOVE:
switchport trunk encapsulation dot1q
switchport mode access
(any other commands)
This SHOULD fix the problem.... Here's the reason why:
You are encapsulating most of your ports with Dot1q tagging, however (assuming here) you're Windows 7 network settings are not specifically sending tags/associating with any VLAN - **MEANING** you're on VLAN1, which has no ip address and no DHCP...
If you're really hell-bent to keep your ports as dot1q, you'll need to add the following command to specifically tell your switch that *IF* there are untagged packets, to send them to a specific VLAN other than 1.
switchport trunk native vlan xxx
Let me know if this work.... (it should)
