Linux PCs can't lookup internal addresses
I'm having another exploratory foray into Ubuntu as a possible alternative to Windows for some of our workstations, as I'm looking into the feasibility of buying out of our MS School agreement next summer.
I installed Ubuntu a while ago and it looks like it could be a go-er. but one thing's puzzling me: I can't get ip addresses of internal servers to resolve.
Anything outside the school works fine (i've put the LEA proxy in as the network proxy) and software centre etc is fine, ie I can ping bbc.co.uk but not cpsfilesrv1 (a server on the network).
Edit: adding 10.105.* (covering our internal range) to the "ignored hosts" list in the network proxy bit has no effect - is there something else I should be putting in there?
DNS seems to be working fine for Windows workstations, just not Ubuntu.
Terminal Server Client won't connect with a server name, but will happily with an IP address. Oddly, "Places-Connect To Server" DOES work with server names:confused:
DNS security allows "ANONYMOUS LOGIN" read access and It's a vanilla Windows 2003 Network (for now)...
any suggestions where to look (at either end)?
