I have read every posting I can find and none seems to fit or fix this problem. I have the following situation in the 2 school districts I work for. The only difference is that in 1 school the secondary server is NT (but is still hosting a domain) I am using E-Smith server as a proxy server with Dans Guardian. I have another E-Smith server that I use as a secondary server with it's own domain. Both have private addresses and "external" access is obtained by forwarding port 80 through my firewall to the respective boxes. Issue. When using the proxy I cannot get to the "other" E-Smith server by domain name. I can however get to it by ip address. External access works fine. Have tried adding ip to hosts and resolv.conf, have also tried adding it as a virutal domain and modifying hostname. The only thing at this point that works is to add entry to hosts file at workstation. This won't be much fun to do to 500 workstations.
The only thing I can guess is that this has to be a dns issue but don't know enough to try to add a DNS entry into E-Smith. Any help or if you need more info to help please let me know. I have been using E-Smith for about 2 years so I can find my way around relatively well.
Thanks in advance.

My guess is taht this is a DNS issue. Comming from a Microsoft world my experience is that internal hosts with fixed IP-adresses must be defined in the DNS-module of Active Directory. I am not an expert though.
I would expect that the definitions of host names for hosts with a fixed IP-adress should be done in Server Manager, but havent been able to findt this functionality with E-Smith.

I have looked around the /home/dns/named/... area at the DNS records but don't have a strong enough background in DNS to add a record or modify one correctly. If anyone can help in this area please let me know.

Jeff, you should not edit it directly anyway.
Take a look at the "hostname and addresses" menu on the box that you are using as you DNS server (Is it your "primary server"?). Changes in this area automaticaly update DNS, WINS and let you make a static reservations (by MAC address) in DHCP server, if needed.
You scenario probably can be resolved something along this lines:
1. On you "primary" server create virtual domain for the "secondary" server.
2. Change hosts for this virtual domain to point to the "secondary" server's IP address by modifying from "self" to "local" IP and providing correct IP of the secondary server.
3. Report back the results for the benefit of the others :-)

I have tried this and it didn't do any good. I have also setup a new test server in Gateway mode with no luck. Is it possible that there is something in squid that is causing this. If I do not use the server as a proxy and use it as gateway/dns server the resolution works. Only in proxy mode does it not work. Since it is a school that is the primary reason for going through.
