Weird problem. Last week the users were having internet issues where some pages would pop up fine, but if you clicked a link it would error out. It turned out that we had to change the dns server from our local computer to 220.127.116.11 and it started working fine.
Now this week users keep losing connection to applications on our servers. Sometimes they can get on fine, other times they have to restart the computer and it will connect. I can ping the servers just fine, and e-mail and internet work, too.
It looks like if I log on as an administrator I have no problems. The security settings haven't been changed on anyone, so what could be happening?
