Thank you for your help Rowland.
I have done as Andrew suggested with mixed success. The biggest problem
I've found is that the internal DNS is seriously screwy. There are no zone
files for the domain that I can find and no server suggests it's the master
- yet when dc1 falls over they all fall down. I'm going to find somewhere
else to seek assistance with that because it's a bind issue not a Samba
issue, but the 192.168.0.0/22 idea has worked to some degree, so thank you
both for that!
