Can't connect to internet with Windows Server 2008 R2 Enterprise

I am in the process of setting up a brand new server with Windows Server 2008 R2 Enterprise.

My current server is Windows Server 2003 SBS so I was following this article closely since it seemed to detail exactly what I needed to do.
http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_2881-Migrate-Small-Business-Server-2003-to-Exchange-2010-and-Windows-2008-R2.html?sfQueryTermInfo=1+10+2008+30+exchang+r2+server+setup+window

I think I made a mistake when configuring the scope during the install of DHCP services on the 2008 Server when I neglected to put in my default gateway. For some reason, I cannot get onto the internet from the new 2008 server. I am on the domain and can access any computer on the network, just not the internet.

Before I proceed furthur with the migration of the DHCP services, I want to make sure I didn't screw anything up and fix anything that I did. Am I getting ahead of myself here? Let me know what additional information you need from me to post here.

What you describe: being able to access any local machine but not being able to access any machine off your subnet is exactly what I would expect, if there were no default gateway defined on the machine.  It isn't impossible that it would be name resolution, but lets start with the default gateway.

If you open a command prompt on the server, and run 'ipconfig /all'.. paying particular attention to entries for the DNS server and default gateway.  (It will probably be a good idea to confirm the IP address and subnet mask while you are there.)

And I'm making a few assumptions:
1. The IP address is statically assigned on the 2008 Server, (I believe it gives you a warning if it isn't.)
2. You've fixed the default gateway issue on the DHCP scope... and either the scope hadn't been activated before the fix, or you've performed an 'ipconfig /renew' on the workstations which might have received confirmation before you fixed the default gateway entry.
3. Its only the 2008 server, not the clients which are encountering difficulty.

IP and subnet are correct when running ipconfig/all on the 2008 server.
The default gateway is blank and the DNS Servers look like...
DNS Servers .............. : ::1
                                       192.168.3.1
                                       127.0.0.1
Which I think is defintely "not correct" since my 2003 server does NOT show that!

1. Yes IP is assigned

2. The scope has not been activated yet. I was following the instructions on the link I attached and was getting ready to change the lease duration on the 2003 server in preperation for activating the 2008 scope.

3. Yes, right now it's just the 2008 server

Okay, firing up a 2008 machine here...
"Start", right click "network", select "properties"
On the left, select, "Manage network connections", then right click your primary NIC and select properties.

Select Internet Protocol Version 4, and select the properties button.

From there you should be able to configure your default gateway as well as your DNS servers.
Two of the entries you report for DNS are loopback addresses, so unless you are running a configured DNS on that server as well, you'll probably be best served making the DNS entries match what your 2003 servers have.

Ok when I right click network and open up properties I'm at the "Network and Sharing Center"
There is no link to "Manage network connections"
On the left I have...
Contral Panel Home
Change Adapter Settings (This gives me the Local Area Connection icon... There is no NIC icon)
Change Advanced Sharing Settings
Do I need to create a primary NIC?

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Network and Sharing Center is correct.  On the left side of the screen, there should be a list of TASKS, one of which should be 'Manage network connections'.

If that isn't there, below the icons of the network components should be "Network (public network)"... and below that should be a "Connection  <space>  Local Area Connection <space> View status"

If you select View status there, then properties, it should also get you to the correct place where you can select Internet Protocol Version 4.

sorry for the late response but I may have found part of my problem. I have two network ports on this server and only one was connected into the network. The other one I connected to the router (trying to match the 2003 server)
I set up that Network Connection with the same settings as the 2003 Server however I still don't have working internet. If I ping google.com from the 2008 server, it recognizes it as a web address and starts pinging 74.125.67.106 but no replies come back.

For some reason I think I'm closer but still not there yet!

What does the "ipconfig /all" look like now?
And if you have two NICs plugged in to two different locations, should probably look at "route print" too.

FIXED! Somehow I got to "Troubleshoot problems - Network and Internet" and it fixed the problem.
The problems it found were...

"DHCP is not enabled for INTERNET" and it fixed it. Seems to be working good now

Thanks for your help!!
