LMHOSTS file being ignored?

[SD_Ryoko]

I try to configure a host for two of the CNC machines on our network. Works fine on two comps, but not mine.

First I edit hosts and lmhosts manually. And they look like this. This is for WIN2K SP4.

127.0.0.1       localhost
192.168.0.121   FANUCH
192.168.0.122   FANUCG

But after I restart, it doesn't work. So I went to TCIP/IP properties, and used 'Import LMHosts' and imported the file from the machine that does work. But its exactly the same, theres no difference. Heres what it does.

C:\>ftp
ftp> open fanucg
Unknown host fanucg.
ftp> qui
c:\>

Now, Hijackthis.exe told me there was a bogus entry pointing to a bogus hosts file. I deleted that entry and the file. Then I used 'Import LMHosts' again, but it still doesn't work. No matter how many times I save it, what I name the file, lowercase, reboots, etc. Its like it totally ignores it.

None of the KB articles mention anything about lmhosts doing nothing, just how to configure them.

Enable LMHOSTS lookup is also checked.

So the localhost is the computer that is yours? You're on a completely seperate network, which is going to require some more work. My first guess is you have some IP conflicts going on, and you need to solve those.

Make sure your port for FTP is allowed on your personal machine.

No were all on the 192 network; I'm not sure why local host is like that.

The other machines say the same thing.

Well, I'm not sure about the ports.

ftp> Open 192.0...... that works
ftp> Open fanucg...... that doesn't work

Almost like it totally ignores me. I can key in the IP manually, but not the host name

It's really hard to see what you're trying to do, and all the information behind it ryoko. Are you trying to use FANUCH and FANUCG from a dns server on the server itself? Possibly the DNS server is down or not working on the server.

If the 127.0.... is your computer that you are using to try to log into those other ones, it will not work. It can't just automatically pick up another network. It will be looking for FANUCH and FANUCG inside of the 127... ip listing. Switching the localhost to a 192.... address may fix the problem.

Well its the same on the other machines?

The deal is we have two CNC machines (With Fanuc controll units) on our network.

But our old one, you can ONLY FTP to the FANUC machines. One has been labeled G, the other H.

If I type in the IP (192.168.0.122) in FTP it connects to it fine. But the hosts file should allow typeing in FANUCG to connect to it.

suggestions:

1) add #PRE to the lines in the lmhosts file

i.e.

127.0.0.1 localhost
192.168.0.121 FANUCH #PRE
192.168.0.122 FANUCG #PRE

entries marked with #PRE get loaded into memory when you logon to Windows.

2) Go into your command prompt and type "nbtstat -R". This will register the names you entered into the lmhosts file. Now look at your netbios cache to see if the lmhosts values have been added. To do this, type "nbtstat -c"

lmhosts

192.168.0.122    fanucg #PRE
192.168.0.121    fanuch #PRE

NBTSTAT -R

C:\Documents and Settings\Dan>nbtstat -r

    MIKE           <20>  UNIQUE          192.168.0.4         460

The Result.....after reboot

C:\Documents and Settings\Dan>ftp
ftp> open fanucg
Unknown host fanucg.
ftp> qui

Lastly I'll say, Hijackthis found a bogus entry for HOSTS pointing to a bogus file. I removed the entry, but now does WIN2K know where to go?

It should have a default for where to go if no entry is found.
