Xbox Live Rebooting The Console...?

[Neipas02]

Alright guys i'll try to explain this as well as I can..

-Xenium Ice is installed on a V1.6..
-Everything is setup and working fine
-Network connection is slightly above simplistic.

1. Running off a router (wired) to NIC #1
2. NIC #2 is running to the Xbox
3. ICS (internet connection sharing) is enabled on NIC #1
4. When I run through the connection trouble shooter on Xbox Live
everything gives a green light (all settings set to automatic)
5. Right when the xbox is about to connect to the live GUI there is hard
reset back to the Xbox Logo and then the MSDash. The console literally
resets itself.
6. XboxConnect works fine. (there is a crossover cable going to NIC #2)
7. Now i'm guessing its due to either the chip or the network setup
i.e.(Ip numbers and ICS)? I really don't think I was banned from Xbox
Live since I don't get any error messages.. and I never remember trying
to get onlinewith the chip enabled. I've never read about this
specific problem on the boards so i'm not sure what it is..
8. I can still FTP to the xbox..
9. I've tried a straight connection from the xbox back to the router (no go).

Any suggestions.. or maybe you've heard of this?
