Scott - It is always best eliminate reliance on DNS.  Of course, some
organizations may require it.  HTH

So for those of us that will be upgrading to 6.x............ which is the
better method?  With or Without DNS.  

Thanks

DNS is not required for CUCM.  That said if you have configured a DNS
server it is required that the server be able to do a dns reverse
lookup on itself and every other server in the cluster.   So if
configure a DNS server during installation, DNS has to be operating
properly.  If you don't configure a DNS server, then don't worry
about it as the hosts file on each server should get populated with
IP address and hostname info during install.

Did you add the subscriber to System->Server on the pub before the
install?  This is what allows the sub to talk to the pub's database,
etc.  That error sure sounds like a connectivity issue.

I have run v6 before without DNS, and had no issues.  I cannot locate
the documentation where DNS is a requirement.   AFAIK, you just need
to change all IP addresses in the Enterprise Parameters to their IP
addresses (Cisco's recommendation).

Yip, the are on the same subnet, same 6500 switch. Publisher is x.x.x.
10 and subscriber x.x.x.11. I see Chris mentioned that DNS is
required in 6.x. I don't know if this is applicable to 5.x as well. I
cannot remember that I had to do this the previous time I've done
this, but will give it a go as soon as I can.

See, that part helps.

OK, are these two on the same subnet? Are they separated by a firewall?
