Internect Connection Sharing or NAT- W2003 Server

[NiferKilroy]

I have a small network, that recently upgraded from a W2K server to W2003 Server running AD and DHCP. My only internet connection is from a DHCP server on the school's network. There is another domain with W2003 Servers that I cannot connect to.
The tech guys can't figure out how to set up a trust, therefore in the past I placed a stand alone W2K Server with 2 NICs in between the networks. Since the W2003 Upgrade, I cannot get Internet connection sharing to work. I cannot send any DHCP broadcast messages out.
Do I continue with another pc in between or can I use NAT or ICS on the W2003 Server. I just can't get anything to work. I am missing something very basic!
Thanks for your help!

Placing a computer with 2 nics is not the best work around...

You have mentioned that you have upgraded a w2k srvr to a 2k3 srvr with AD and DHCP.....and yet using the DHCP server from the school network, having two DHCP is not the problem but if they both provide the same range of IP address then that could cause issues.

Trust relation between two domain controller could be resolved by adding the name of the computer to the AD list and check mark where it says....."TRUST THIS COMPUTER" , or you could issue security certificate by both domain and install them on both system (it's not a simple solution).
