DNS Mystery

[dazzieb]

We have a client who has a small network and windows 2000 Server. Their local domain name is the same as their web address without the

http://www prefix.

We set up a forwarder in DNS for the "www" aspect which was all working well for a while. It then stopped working and the only temporary solution available was to set the users to use the Win 2k server IP address as the primary DNS and their ISP's primary DNS as their secondary DNS. This worked a treat (bearing in mind it was a temporary solution).

However, someone has now told the client that anyone who prints to a shared printer on the network, is now sending all of their documents out across the net. I find this quite hard to get my head around seing as the printer is shared through a user on the network within a private IP range (192.168.blah.blah).

Has anyone ever seen or heard of documents going external like this before? or can anyone clarify if this is a possibility.

Any clarification would be greatly appreciated.

A little knowledge is a dangerous thing. For one, you need a destination before you can 'send' out across the net unless you are broadcasting the documents, which I doubt. You should check your firewall and see what traffic is flowing through it.

As regards your DNS issue above - the configuration you mention looks like the correct one. I would have left the secondary DNS blank and set the forwarder on your DNS to point to your ISP's DNS. Then you can lock down the DNS querying to the outside world to your DNS server only.

Hi Castor66, thanks for the reply.

I agree a little knowledge 'is' a dangerous thing and can unfortunately strain client relationships if not used wisely, as I am sure you will agree.
