First of all accept my heartiest thanks for the eagerness you have shown in sorting out the problem. Yes, ISA server's internal IP address is being used as the default gateway. Extra info for you - when the following command is issued from the linux terminal - telnet domain.com 25 or telnet domain.co 110 It resolves the IP of the said domain but after a fixed interval of time, it displays the message - Connection timed out

No entry found in the ISA log. Message from evolution - Connection timed out

We are using POP3 protocol for our email server and the servers are hosted. Please note that we use ISA server 2000 on our local server and all the workstations have ISA server 2000 client installed on them with static IP (i.e. DHCP is not being used) and the outlook doen not have any problem receiving or sending emails. The two workstations that have Fedora core 6.0 installed do not have any client for ISA server 2000and hence the probelm.

The servers are live with windows server 2003 and Argosoft email server installed on it

I made the changes as suggested and now the internal sites are working fine. However, the problem with evolution remains as it was. Thanks for your nice suggestion.

We have windows Small business server 2003 installed with ISA server 2000. All the windows based clients work fine with no problem in accessing internet or using email clients. The problem is with Linux based clients (Fedora core -6). The problems are following - 1. If the browser is configured to use the proxy, internet can be used without any problem however the users fail to browse the internal websites (e.g. EduGeek.net, etc) (created by adding cnames). IF the proxy settings are removed, the internet cannot be accessed but all the internal websites works fine 2. Evolution email client does not work at all (the connections time out) I am new to Linux and therefore have failed to resolve the problem till date. Any help in this regard would be highly appreciated.
