RE: [squid-users] errors while opening sites

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.
