I am not retina, nor have I been on corporate networks, but in your description I did not see any mention of entering the appropriate password.
I am curious what you mean by "grabbing an IP address"... should the network not assign one to you?

Thanks for the reply. There are no password requirements to connect to our wired network. For wireless, I provide my credentials and am sucessfully authenticated via 802.1x. I also could have been a bit clearer, the DHCP server assigns an IP address automatically to my computer; I don't have to do anything manually for this to occur.

I had to get off line- storm extraordinaire... So, I am new enough that I need to see what your settings are to be of any help... SOMETHING needs changing... I just cannot begin to guess until I see things.
Hopefully, one of the Masters (level 7's and 8's) will come save you before long!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
- Be sure your Mac is shut down.
- Press the power button.
- Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
- Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under Mac OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Thanks for the suggestion; I booted into safe mode, connected to the wireless network, and was able to access network resources without issue. As soon as this happened, something clicked and I was able to quickly determine that the Checkpoint VPN client that I had installed must be the culprit as it has a built-in firewall that can blocks inbound and outbound access. I uninstalled this application, rebooted, and have had no problems since.
Thank you very much for the idea to boot into safe mode; it was the missing piece of the puzzle!
