resolv.conf overwritten with incorrect information

I connect to the internet using a RedHat 7.0 system and an ISDN line.  It seems that my ISDN software is somehow overwriting changes that I make to resolv.conf.  I have isdn-config -0.17-7.6x installed and that is what I am using to connect.

How can I fix this problem?

Give only reading permission to resolv.conf.

No.  I found what was overwriting the file.  The ifup-post script overwrites the file with the information returned by my ISP.  For some reason they are returning invalid information.  That script is run set uid to root so changing the permissions wouldn't help.  I took out the part of the script that overwrites the file.

However, I still have a problem that even though I am able to query the DNS server and it returns the correct information I am still unable to get my browser to be directed to the correct server.  The browser is still being directed to the old IP address.

I ended up resolving the issue by reissuing the request to the DNS to update the change of IP.  It seemed that there was a propagation problem that was getting in the way of resolving the address.  Please close this question and refund the points.
