SBS2008 no external connectivity every startup, must run Fix Network wizard

I think probably from installing an update (and I wouldn't know which one), or from trying to set up a Smart Host (which I have now removed as it was a bottleneck nightmare and corrupting my Exchange transport), every time I restart the server, there is no external connectivity until I run Fix My Network wizard.

It states I have an incorrect network address type, and it goes away setting my server a fixed IP address.  I know that my IPv4 and v6 addresses are static, and they are static even after start up, and before I run the wizard.  My guess is a DNS issue, but don't take my word for it.

Thank you

If you ping www.google.com for example does it resolve?

Rather than run Fix My Network, what happens if you try a IPCONFIG /FLUSHDNS from the server? Also, go into DNS Manager, right click the server name and select "Clear Cache".

Thank you,
I have tried the Clear Cache in DNS, and I will test the scenario later today.
I don't think that external DNS would resolve under this lack of connectivity.
Obviously my trouble is I have to be at work out of hours to try.

Hi,

This is a know issue with SBS 2008 issue, it will loose its default gateway after a reboot. The problem is that there is a empty line in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<GUID>\DefaultGateway registry key. Removing this line will solve the problem.

full solution is in the article: http://blogs.technet.com/b/sbs/archive/2010/04/22/you-may-lose-the-default-gateway-on-sbs-2008-every-time-you-reboot.aspx

Thank you for that info.
Certainly describes the situation.
I have applied the changes, but will wait to restart to test, really appreciate the advice.

All fixed thanks.  I had to re-enter the gateway ip afterward, don't know why, it seemed fine in the registry setting, but it worked - thanks.
