SUMMARY

You have swapped the internal network card and the external network card on Small Business Server 2003. CEICW gives errors relating to DHCP and will only offer you the original LAN NIC as the WAN option on a Direct Broadband connection.

SYMPTOMS

The Configure Email and Internet Connection Wizard (CEICW) only offers you the original LAN adapter as an option for WAN connectivity.

CAUSE

This is due to an entry in the SBS2003 Wizard registry settings that points to the GUID of the LAN network card that was initially set on the server.

RESOLUTION

Determine the Network Card GUID's

Open the file "c:\program files\microsoft windows small business server\support\icwlog.txt
Search for the text "LAN NIC Guid" and copy/note the GUID beside this text.
Search for the text "External NIC Guid" and copy/note the GUID beside this text.
Close the file

Change the GUID in the registry

Click on Start, Run, then type "Regedit" without the quotes.   Click on OK.
Within the registry editor, browse to the following location:  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer
On the list of entries on the right of the screen, you will see an entry called LANNIC.
If you look at the data of this entry, you will see that the GUID is set to that of the External NIC and not the LAN Nic GUID's that you noted earlier.   You must edit the LANNIC entry to the correct GUID that you noted earlier.

Rerun the Wizards

Open the Server Management Console from the top of the Start Menu.
Click on "Internet and Email" on the left column.
Click on "Change Server IP Address" and set the IP of the server (even if it is already set).   This will reset the Small Business Server DHCP, DNS settings for you.
After the wizard has completed, run the "Connect to the Internet" wizard again and the LAN card will show correctly.

Other Comments

Ensure that the network card that is now you LAN adapter has "Enabled Netbios over TCPIP" enabled under the WINS tab.  This option is disabled on the WAN adapter.
