my $0.01, without DNS.<br>
<br>
With DNS means your dialtone depends on DNS. If your dialtone and DNS
have the same level of SLA including monitoring then may not be a
problem. When DNS enabled CM depends on both forward and reverse
resolution. Few organizations appear to create and monitor both
records by default.<br>
<br>
With DNS enabled any DNS downtime or delay directly affects call
processing, intercluster communication, and service activation/install.<br>

is not required for CUCM. That said if you have configured a DNS<br>
server it is required that the server be able to do a dns reverse<br>
lookup on itself and every other server in the cluster. So if<br>
configure a DNS server during installation, DNS has to be operating<br>
properly. If you don't configure a DNS server, then don't worry<br>
about it as the hosts file on each server should get populated with<br>
IP address and hostname info during install.<br>
<br>
Did you add the subscriber to System->Server on the pub before the<br>
install? This is what allows the sub to talk to the pub's database,<br>
etc. That error sure sounds like a connectivity issue.<br>

I have run v6 before without DNS, and had no issues. I cannot locate<br>

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

See, that part helps.<br>
<br>
OK, are these two on the same subnet? Are they separated by a firewall?<br>
