DNS Question (from a novice)

[Mathew Plumb]

Apologies for the possible vagueness of this question but I'm a complete
novice to DNS and have been thrown in at the deep end a little.

Here's the deal :-

I'm running Netscape Navigator 4.08 (over a corporate NetWare 4.11
LAN/WAN) via a WEBsweeper proxy server through a Cyberguard firewall out
to the Internet. Now if I set the browser to make a direct connection to
the 'Net everything is just fine but if I set it to go through the proxy
server it takes for ever and a day to respond. More often than not it
times out.

However if I go to a MS-Dos prompt and run a tracert to the proxy server
and then go back to the browser everything is fine. This is the only
clue I can come up with and it works everytime.

Any ideas? Anyone? Please?

Regards

Matthew

ps. Hope I don't sound too desperate <g>
