You need to make changes to the LMHOSTS file on all the CC3 DCs and recreate the build disk. I can send some instructions if you like.
Sorry for the late reply.
Just wondering the changes you had to make to the CC3 DCs in order to get them working on VLANS.
The VLANS are working fine, but building a CC3 machine isnt as it fails to find the server via DNS. I'm not sure if this is a seperate DNS issue or not!?!?!?
