DHCP is being racist, going crazy

[jaroszke]

Hello I have a ASA 5510, I posted before about dhcp and figured the problem out, but now have a crazy problem. I have a sub interface going to a vlan on a switch, and have it setup to get dhcp from the asa and the asa is pointing to an internal DNS server on a windows 2008 box. Four of the same type of computers obtain ip addresses but 4 pc that are different brands than the other won't obtain ips, they all are running windows 7, and also 3 imac are not obtaining IPs either. These computers are all on the same vlan on the same interface of the asa. The crazy part is, if I take the cable pulled into the computer not getting an ip address and plug it into my laptop running windows 7 I get an IP. I also took a default router setup with dhcp(linksys plain old router) and the computers that aren't getting ips will get one with that router. So that doesn't seem to help narrow anything down. I also looked at the APR table and it show the asa is giving out address but windows is still assign it the 169.x.x.x address.
I have also tried setting a static IP on those computers and it is not working. I am puzzled, Anyone have any ideas?
If you need my running-config let me know if that will help Thanks

Config would help....

Okay I figured it out I think, I went and picked up a cheap network card and put it into a PC that wasn't working and pulled in the cable and it worked, so then I started looking at the configurations on the onboard network card, and under configurations on the network card there is a setting Priority & VLAN, it was set to priority enabled, I switched it to Priority and Vlan enabled, so I set that, still didn't work, then another option was vlan id so I put in ID # 3 and it worked. I think its stupid how you have to manually set that, especially from a management perspective, anyone know a way around that the onboard network cards are " Nvidia nforce networking controller"
But that leads me to a problem with the iMac computers, I cannot seem to find that option. Anyone know where that might be?
