SBS2003 with intermittent client DNS connections

Hello Experts,

I have an SBS2003 server (my own) with intermittent DNS problems. I have an XP desktop and two Vista Ultimate laptop clients that are all showing intermittent Internet connectivity problems.

I may have caused this when I was attempting to replace an SBS generated certificate with a new GoDaddy certificate right before I left on vacation and got lost in the process (never successfully completed).

I tried running the Internet Connection WIzard but that did not help.

Any suggestions would be greatly appreciated. Thank you.

Below is the result of an ipconfig /all from one of the laptops:

Hi demazter,

Do you mean turn off ipv6 in the SBS MMC (and then re-run ICW) or by using the netsh command?

I found a reference to running netsh from a command prompt and then using the following command to uninstall ipvt from SBS2003:
(command prompt)
netsh
interface ipvt uninstall

Thanks for the response.

just uncheck it from the properties of the network card on the server and the clients.

I thought I should post a final note. I found an old pc and successfully added it to the domain which indicated a problem with the Vista laptop. I then rebuilt the laptop and successfully ran the connectcomputer command on the laptop BEFORE adding any other software or Windows updates.

Apparently, there is an update orpiece of software that was interfering with the connectcomputer process.

I hope this helps someone else.
