Dear Amos, Thanks for the reply. We are using the same DNS servers for our existing proxy server which is ISA2000 & is working properly without any problems. We want to shift from MS-ISA2000 proxy server to Linux Squid proxy server, so we are building up this new proxy server. More over if I access the internet from the Ubuntu proxy server itself, we don't get any such errors. Can you / anyone let me know how can we resolve these issue. Also for your information that, so far ubuntu server is just a member server in our enviornment & there is no DNS server configured in Ubuntu server. May be this will help you for finding some outputs. ~~~~~~~~~~~~~~~~~~~ Thanks & Regards, Sameer Shinde.
