Demand Dialup DNS resolution

I have configured a shared internet connection with demand dialing and when I access a site outside my network from a machine other than the server it quite happily dials out. If I have specified an IP address for the site then it connects and displays the site happily.

If I specify a domain name however it can never find the site.

The server has a DNS server on it which lists the sites and machines on my network, The client machines network connection utilises a dynamic dns server allocation (although I did have this fixed with the IP of the server but this made no difference).

The dialup connection on the server also uses dynamic IP and DNS allocation.

It seems to me that the root problem is that the name is not being resolved. I can understand why my DNS couldn't resolve it but I'm not sure if I have to do something to 'pass' the resolution on to the dynamically allocated one on the dialup connection.

Can anyone offer any advice or help.

yhe ISP should have a DNS server IP adress that you could add to you're machines manually or through a dhcp.  Telling the machines to lookup up on the local dns server or the others secondary servers(ISP DNS).

Did not hear you mentioned about using DNS forwarders. You should add your ISP DNS as forwarder in your internal DNS server and dont forget to set the default gateway at DNS server to the computer you used for internet sharing.

Corvex: I tried this both ways round to no effect.

Hnminh:

The server is a root server so it won't let me add a forwarder however according to the Mircosoft help root servers forward on to the servers listed in the cache.dns file. This has a number of dns in it which are reachable.

I also tried adding my DNS and my ISPs DNS to the DHCP but again to no effect.

One thing I have noticed is that in the DNS log file when I make a request for www.yahoo.com the first question and response contain this name.

However there is a second question response pair that refer to www.yahoo.com.bedrock.co.uk

Now bedrock.co.uk is the name of my one of my zones and the DNS server actually sits on this domain. To be honest I'm not to clear at waht I'm looking at in the DNS log file but I was wondering if I have named my zone wrongly?

Thanks Corvax.

The actual answer which is partly suggested from your two references (although MS suggested you needed to do more than you have to) is just to delete the root zone ie "." and hey presto it works.
