Hi

We have setup a SBS server and disabled IPV6, we realise now we shouldn't have done this but can not get back into network settings to re-enable.

We think the only way to get this work is to go into Safe mode with Networking but cant do this as we get this error

"The security database on the server does not have a computer account for this workstation trust relationship"

If we just reboot the server and start it in normal mode it sits on Apply Computer Setting  for over an hour.  When we do login cant launch any apps

Cheers

There should have been no issue with disabling IPv6. I am running sbs 08 with dual NIC and disabled it on both with no issues. Did this issue just start after disabling IPv6?

Proper methodology:

There _are_ issues with improperly disabling IPv6 on SBS 2008 as the various components within the product use IPv6 to communicate.

Leave it on. Disabling it impacts the server setup, was a part of the original design structure, and really there is no real good reason to disable it.

BTW: Only 1 NIC is supported for a _proper_ production setup of SBS 2008.

Some further thoughts on disabling IPv6:

We already know that disabling IPv6 is a bad idea, the problem is how to re-enable it.  As we can't get into Network and Sharing once we have logged in, is there a command we can use to re-enable it? without using the gui screen?

Start --> NCPA.CPL [Enter]

That should get you to the list of NICs and allow you to bring up their properties to tick IPv6 again. Can't remember if Safe Mode allows for that or not.
