INTERNAL ONLY my DNS will not recognize my ftp://brenprint.com. It will recognize the ftp IP address. My www works just fine. I have already disabled the following services on that NT Server running NT 4.0 sp5:
ftp publishing services, gohper publishing services, www publishing services. My DNS entries match my old server, so I'm lost. Any Ideas ??????

SYNTAX:
First re-enable the FTP service. Then try to connect, on your internal network, to the computer via a client command prompt with the command "ftp brenprint" see if it sees the computer. This will find out if it is a syntax issue or not.

ACCESS METHOD:
The method of access was not mentioned. The fact that "www" was brought up, leads me to believe you are using a web browser to access ftp. Typing ftp.brenprint.com should work if the service is enabled, since the "www" access is there(same protocol, same method of resolution).

NAMING SCHEME:
If you are internal, you do not need the ".com" unless the host name is such. If it is "brenprint.com", change the host and NetBIOS names are "brenprint".

".com" in a host name will cause nothing but pain.

SECURITY:
Make sure the default port has not been changed for the "ftp" service. If it differs from 21 the client ftp app has no idea what to access.

I tried it but it didn't work. Yes I am accessing ftp thru a browser. I also deleted the record in DNS then re-entered a new record, still no luck.

1) In DNS there are two entries in two files for a server, one in and one out. Ping from brenprint (as a hostname) to your machine.
If that works, than you are missing a DNS entry.
Entry one starts with the IP address
xxxx.xxxx.xxxx.xxxx in-addr........hostname
the second file starts with the hostname
hostname -in ....... xxxx.xxxx.xxxx.xxxx
1b) If the ping does not work, check levels of IP, IPX, TCPIP or DHCP.....
I have had the problem between a rel 4 and rel 6 IP or IPX machines. If one is a 6, and the other a 4, a netsvc.cfg file (for Windows) or netsvc.conf (UNIX/LINUX) has to be created in the 6 system.
\winnt\system32\drivers\etc (Windows 2K or NT)or /etc if a UNIX/LINUX box
Should contain:
local4,bind4
This allows downward compatible comm.
2) Is there a network route defined from the DNS server to your machine, or vice-versa.
From your machine:
tracert ip.address.of.dns.server (windows)
traceroute "" "" "" )UNIX
From DNS server:
tracrt ip.address.of.your.machine
If fails, DNS is not able to function
3) Is there an entry in the 'services' file that allows ftp????
Look in /winnt/system32/drivers/etc/services file (N/T or 2K)or /etc/services (UNIX)
for an entry that starts with
ftp tcp/23 or check in both servers and make sure they match. (sometimes standards are deviated from to discourage hackers if ftp is only internal)
4) Make sure that 'named' (a task in windows a daemon in UNIX) is not running on your machine
5) Make sure DNS is configured on your machine with the i.p address and netmask of
your DNS server, and NOT the hostname. (cannot be resolved until it gets to the DNS server).
6) Make sure that a native .hosts file is not overriding a DNS.
7) Since you are talking about a new machine, make sure that two machines with duplicate ip addresses or hostnames are not running on the network at the same time.

Try ftp:\\brenprint

Check MS' Knowledge Base; ftp with the browser may have been patched--it's been more of a fantasy than a working feature.

Get a real ftp client! FTP Explorer from ftpx.com works like a champ and is almost free!

by brian.pyle

As usual it's the simple things that cause problems. I needed to create a new "A" record for Brenprint.com and also a new zone for reverse intenal lookups which included two PTR records one for Brenprint.com and one for ftp.brenprint.com
