DNS is not reachable

[Jay Azimi]

Hi,

 

I have a network run under Windows 2003 server with

About 13 stations.

 

At least 5 times a day I cannot open a page with Internet

Explorer or Firefox or any other browser. The error message

In all these cases is ; DNS in not reachable.

 

Even if during this time window of about 2 minute I jump on

The server the problem is the same.

 

More interestingly, during this time modem shows that the

Internet connection is on and the radio I listen to from the 

internet  does not get disrupted. After about 2 minutes its is

all back but it is very frustrating.

 

Help.

 

Jay
