Windows Server 2008 R2 cannot access internal and external Network

Dear Experts,

I am facing a major communication error on my Windows Server 2008 R2 which hosts the following:

-Domain Controller (there is no secondary)
-DHCP Server
-SQL 2008 Server
-Exchange Server 2010 SP1
-File Server

What I did:
I was trying to create a TEAM Network between the 2 physical Network Cards of the Server.
I noticed that the server had 3VLANS that were not in use and 4 Local Area Connection virtual adapters.
The server was connected to the Local Connection 6 (and the local connection 6 ,which was virtual, was somehow assigned to the Physical port)
I decided to delete all the virtual adapters and keep ONLY the physical ones.
So the server has now only 2 physical adapters available under Network Adapters.

What is occurring now:
After using the same IP Address, Subnet, Gateway and DNS Servers I noticed that I could not connect neither to the internet (from this server) nor to the rest internal network (from this server)
I cannot also connect to the Exchange Server via OWA

I have tried to:

-Restart Server
- Disable IPv6 from the Local Adapter
-Perform Flush DNS
-Change the DNS to 8.8.8.8
- Use the troubleshooter of Network Adapter
- Disable DHCP
-Use the remaining Network Card

I am attaching you the ipconfig results for your reference.
ipconfig.txt

Please advise asap since in less than 12hours the users will have to use the Server’s Applications and File Services.

Thanks in Advance,  
Mamelas

I have uninstalled both Network Adapters and Scanned Network Configuration
in order to add them again.

The Server is now having access to the Internet and the Local Network but
i still cannot connect to the Exchange Server

does the exchange server run in hyper-v?

DNS Servers . . . . . . . . . . . : 10.1.1.1
                                       8.8.8.8    << remove this and use your dns forwarders tab>>

Dear David,

Thank you for your prompt reply.

This is a physical Server.
The Alternate DNS Server , 8.8.8.8 , is not the cause of the problem.

My Exchange Server is down and I found from the Net that I should enable the IPv6 option
to my NIC...

I will try...any other ideat in order to restore Exchange Server's operation???

So for my case the following two actions solved my problem:

- Uninstall the Network Adepters from Device Manager and perform Scan for Harware changes
  (with this step the Network was restored)

- Enabled the IPv6 option under Network Adapter
  (with this step the Exchange Server restored sucessfully)
