SBS 2008 migration issue

I am at the point of running post-migration steps after a SBS 2003 migration to SBS 2008.  I run the "Connect to Internet" Wizard and everytime it fails on "connection Incomplete.  Cannot configure DHCP for IPv4 networks".  I have restarted the DHCP service on the destination server multiple times, but that did not fix it.  i tried the "Fix my Internet" wizard, but that did not fix the problem.  I think i may have removed IPv6 (I wanted todo so) because i was gettings errors saying that the NIC had a dynamically assigned address.  Does anyone know how to fix the DHCP issue?  Thanks for any help that anyone can give me.

Hi,

have you configured the NICs on your new SBS to have a fixed IPv4 address?

Yes.  There is 1 NIC and it is 192.168.10.10.  The router is 192.168.10.1.

Do you have any other devices on the network that may be advertising DHCP role (old SBS or router)?

The old SBS server is, so when prompted i stopped the DHCP Server service.  Still got the error.  Restarted the Connect to Internet Wizard on 2008 and still got the same error.

You mentioned that you've disabled the IPv6 on the NIC. Do you mean that you disabled the IPv6 protocol or that you've set the IPv6 address to some fixed address?

Also is your new SBS possibly a virtual machine?

The new server is not virtual.  I could not set a static IPv6 address anywhere, so that is why i tried to uninstall ipv6.  I cannot successfully move the Exchange databases to another drive, nor move my Sharepoint website.

OK,

lets stick to DHCP issue for now.

could you please run the ipconfig /all on new SBS and post ouput here?

Also please navigate to the registry settings for your NIC under

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{NICID}

and please post the contents of the key here.

Tomislav

I am more concerned about DHCP, anyhow.

There are actually 2 keys now.  Let me see if there are 2 NIcs in the server.  Device Manager only shows 1 NIC.  However, I do see 2 network ports.

I am not getting any errors in Event Viewer when it fails to finish the Internet wizard because of DHCP.

I'll be signing off now, I hope you've made some progress.

Explanation of registry check
The goal of my previous request was that you check that the IPAddress value in the registry key cointains the proper IPv4 address and no IPv6 address (if you've disabled IPv4). If IPv6 address is still there after you disable IPv6 try removing it from the IPAddress value (leave just the proper IPv4 address of your NIC). PLEASE BACKUP THE REGISTRY KEY PRIOR TO ANY CHANGES.

If you aren't sure how to find the GUID of your NIC then type "net config rdr" in elevated command prompt. The GUID should be displayed on the left and NIC's MAC address on the right. The MAC address of your NIC can be found if you right-click your NIC in network connections, choose Status and then click Details (MAC address is the value in Physical Address).

Check DHCP server properties
If all is well in registry (or after you fix it) check that your DHCP server is bound to your NIC IPv4 address. To do so go to Administrative tools > DHCP, right-click your servers and choose Add/Remove Bindings... Check that there is a check for your 192.168.10.10 on IPv4 tab. Since you disabled IPv6 there should be no entries on IPv6 tab.

Also check that your DHCP is authorized in Active Directory. If it isn't authorize it by right-clicking its name in DHCP management console and choose Authorize.

I hope some of this helps. If not I'll check in tomorrow if no one else helps you to resolve your problem in the meantime.

Regards,
Tomislav

I've only noticed your last post after submitting mine :)

Check my comment for directions on how to find your NIC GUID. Also, your NIC still obviously uses IPv6 address (meaning IPv6 is not deactivated).

I logged on as domain admin and authorized my DHCP server.  I think it may have been already authorized, though.

Don't unbind IPv6 for now. Just make sure that you have bindings for IPv4.

And don't be alarmed about multiple GUIDs in the registry - they are created for some virtual and pseudo interfaces too.

If you want to temporarily disable IPv6 on your NIC then deselect the checkbox for IPv6 protocol in your NIC properties.

After that you may be required to restart.

Does it matter that my default gateway is actually a Cisco PIX (not a true router)?  My DSL modem/router is outside of the internal network.

Well, your default gateway should point to a router that you use to access IP addresses that aren't in your LAN subnet (like internet or separate LANs).

Have you checked there are no AD or DNS related issues on your new SBS?

Since you have problems with DHCP, WSS, Exchange and stuff there may be access problems with your drives that shouldn't happen if you are administrator.

And also now that you've mentioned it - have you run the migration and Connect To Internet/Fix My Internet Wizards when logged on as domain administrator or not?

Sorry I couldn't help you.

One last thing, what errors are reported when you run dcdiag /c? (They'll probably ask for that at some point too if they don't have a ready solution).

I called Microsoft and he called me the next morning while I was onsite.  He ran some diagnostics from the command-line and renamed the CTIW log file.  He then ran the "connect to Internet" wizard and it completed the first time.  I am still unsure exactly why it worked for him and never did for me.  After it succeeded I was able to finish the migration.
