I have 2 domain controllers
one ending with .12 (domain name aaa) and second ending with .15 (domain name bbb)
The plan was to move all PCs from domain aaa to domain bbb
aaa is a DNS, DHCP, print server, file server and AD
bbb supposed to be DNS, DHCP and AD only
I created a trust between aaa and bbb, every thing was going smooth
Istart moving clients from aaa to bbb with no issues until aaa failed
At that moment I made bbb DNS and DHCP, every thing was good an the moved expedited with no issues and no data lost
One day, I had to reboot bbb, here the problem starts
Out of a sudden no one can access the internet except bbb itself
At this point I digged in and found that forwarder still pointing to .12 not .15
I tried to add the .15 to the dns forwarders and I got the following error
The server forwarders cannot be updated the IP address is invalid
