That's probably expected. I don't think nslookup can query multiple DNS
servers at once. But is DC4 actually responding to DNS queries? Compare
"nslookup <domain> <DC3-ip>" and "nslookup <domain> <DC4-ip>", which will
hopefully tell you that both DC3/DC4 are capable of answering queries.
This DNS timeout on "standard traffic" is probably what you need to figure
And I hate to ask, but are both samba and bind set to automatically start
after boot (on the DC's)?
