Hi,
Ifthis is theproblem!You can not changethe domain andDNS,becausetheVCinstallationandconfiguration of theDBpoints toFQDNof origin.
For the resolution:
Remove from old domain, reboot. Add to new domain, reboot.
In the ODBC use SQL authentication, because Windows will not work if the 2 domains are not trusted.
Regards
Daniel
