Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

We have Ubuntu on or network (AD). The server is Windows 2003 and Kerio Control is running as firewall on it.

All windows client are using Internet correctly but one Ubuntu client could not browse the Internet.

I get this message in browser when trying to connect :

Server not found.
Firefox can't find the server at server.company.local

any help is appreciated

Sounds like a DNS problem to me. Is the Ubuntu machine using the same DNS servers that the Windows clients are?

Yes, all clients are using the same DNS server –  Omid Amraei Feb 6 '12 at 13:46

http vs. https?

Or did you perhaps define some access control like only allowing specific ip-ranges to access a service?
