Hyper-V Virtual Server missing from list

Hey there,  I have an SBS2008 premium unit with hyper-v activated

I installed a virtual server for terminal server use, everything was set up properly and working.

I had to mess with the rdp port on both the sbs server and the virtual server session so I could install this server side by side with an existing installation and have access to both units for file transfer.  When I did this, I had to mess with the windows firewall on the sbs2008 to allow the new port to have access.  I even turned off the firewall to make the new port access work.  I got tired of fiddling with it and returned everything in firewall to the original state,as well as the RDP port for the SBS2008 to 3389.  I went to the Hyper-v manager and my virtual server was missing in action.

I can browse to the Hyper-V file area and I see parts of my configutation still there, but in the hyper-v console it is indicating 'no virtual machines found on this server'

If I look at my network adapter settings, originally there were 2 adapters,

 one was called Main 192.168.1.10 with the gateway of 192.168.1.1
the second was called second 192.168.1.5 with no gateway listed

When I installed hyper-v I assigned it to the 'secong' NIC

Then a 3rd adapter appeared 'local area connection 2' with the 192.168.1.5 address and the gateway of 192.168.1.1 and the 'second' adapter had everything in it's properties unchecked except for 'microsoft virtual network switch protocol'

So I need to do 2 things:

1.  Get my virtual server back (and I'll do an export this time for safety)
2.  get the MAIN network adapter to list the gateway, it will not take it right now because of the 'local area connection 2' having it from the virtual machine

Thank you for any help

Is the Hyper-V Role installed _on_ the SBS 2008 box/OS?

The Hyper-V Role should _never_ be installed on SBS 2008.

This is not a supported scenario.

Hyper-V messes with the TCP/IP stack. SBS 2008 and the wizards that put the box together when you run them rely on that stack staying in the default configuration.

Look for DNS and DHCP to start misbehaving on you as well as client computers no longer connecting.

If you have SBS 2008 Premium then do the following:
 + Install Windows Server 2008 on box.
 + Enable Hyper-V Role
 + Install SBS 2008 OS into VM in Hyper-V.
 + Install Win2K8 OS into VM in Hyper-V.

That is a supported configuration where both SBS 2008 and Windows Server 2008 run as guests on the Hyper-V host. To remain properly licensed you can only run the Hyper-V Role on the host.

Remove the Hyper-V Role from SBS 2008 and run the Fix My Network Wizard to make sure that your networking is not totally horked.

Not what I wanted to hear, but it was what I was expecting!

At least it happened now before it went into production.

Thank you!
