I don't see anything with the same IP in DHCP and different MACs
Seems if you let it sit for some time it will connect.

Have you cycled the power on all of the infrastructure devices ( DHCP server, Cisco 5508, and the AP's)?
And/or are there any iPads, iPhones, or iPods also connecting?
operationsITAuthor Commented:
APs?  Server and controller yes
Davis McCarnOwnerCommented:
I asked about the iDevices because they violate standard DHCP protocol and and try to take their last ip, only initiating DHCP when that fails.
Two other thoughts.......
How long is the DHCP lease timeout set for?  The router I use to connect client PC's to gets 50+ each month and I have to cycle its power periodically because it gets confused and won't let them connect.
Also, some NIC's now use a software MAC address that I have seen be the same through multiple PC's of the same model.
operationsITAuthor Commented:
We have DHCP reservations for them so they should continue to get the same IP.

8 days - default lease time

Can you post one of the Dell's service tag numbers?  Then I can explore the MAC address problems specific to that PC.

I.m sorry, I never got the email saying you had posted.  Did you get this resolved?
operationsITAuthor Commented:
Not yet but been googling and trying things
Davis McCarnOwnerCommented:
The service tag you posted came with an Intel Centrino-N 6235 wifi card and I would suggest you focus on it. Did you find this?
