My network setup is as follows:
Gateway IP: <Router>
DNS Server: <SBS2003>
SBS 2003 is my domain controller/DHCP server and handles all my DNS queries. All DNS queries for the Internet are configured to go via SBS which then points them at the router and uses the DNS servers on the router (my ISP) to lookup the address.
However, I'm finding some sites are working, but others aren't. The sites that are resolving in terms of DNS are taking an age to load. The Microsoft site loads, but with no CSS and tons of HTML-related bugs.
Apart from that the Cisco drops every few minutes and reconnects. It makes an audible 'click' noise when it tries to reconnect - is this normal?
It's running ISO Software 12.4(4)T8. Could a software update fix all these problems?
Finally how does the reset button work on the back? Sounds silly I know but I've tried pressing and even holding it in for a minute, but nothing happens.
Any help would be greatly appreciated. Thanks in advance.
