Windows 7: Sharing Permissions for a NAS server raid volume

Hey all,
I have been beating myself up over this file sharing thing. Brief explanation of the system setups. I have a work computer that serves as a camera surveillance server with a third party program. All is fine with that, in fact never better. The cameras use the #1 NIC for the data for the surveillance program to record it and all that jazz. The time has come for more storage, so I made a NAS server of sorts with a raid controller card 8 x 2TB hard drives in RAID 5. Again all is well with that setup.

Incoming problem

On the camera server computer, lets call that comp. A, the #1 NIC is lan connection 1 setup as Work Network. #2 NIC is connected to the NAS server via a crossover cable. Both computers are part of the same work group called CAMERASERVER WORKGROUP. When they are both connected, the second network connection comes up as Unidentified Network (Public Network). This is not a big deal to me since from computer A I can see computer B in the network and can access the Public shared folder on computer B. But I am trying to share the raid volume designated disk E: at 12.7TB. When I right click the volume E: and select share with, I can create a share folder named NAS archive. Then on computer A I can see that shared folder, but when I try to double click into it like I do on the Public share folder I get a permissions error.

Says something to the effect of "You do not have permission to access \\xxxxxx. Talk with your network administrator to... you know the rest. Obviously I am missing something on the computer B side of the equation. I looked into the permission on the NAS archive folder and I can't see any user or computer on the computer A side to allow share permission.

Both computers have their network sharing permissions set the same,
Network Discovery = on
File and Printer sharing = on
Sharing for anyone = on
Password protected sharing = off
Use user accounts and passwords to connect to other comps = on

Any suggestions would be appreciated.

I figured it out. Not like the old XP and server 2003 ways.
