A customer of ours has a T1 with us. We connect into a cisco 1700 router and from there to a switch. We can ping www.yahoo.com from the router from swith and from the desktop pcs, but no one on the LAN can actually browse the internet. Also we tried doing the IP address as well. What can cause this issue. Seems like when we reboot the router it works for about 24 hours and then goes back down. But rebooting isnt the option for this company as they have no IT staff. Thanks in advance for the suggestions.

Basically I thought it was a DNS issue, but when we went to type the IP in the browser the website did not come up-- neither with the web address. We can ping www.yahoo.com as well as its IP address but they cannot browse any websites or receive any emails on their LAN. There is about 10 computers and I work remotely, so i do not have access to a console. Thanks
