    I cannot connect to any site which has to do with Nasville government.
    (nashville.gov, library.nashville.org, etc.) All other websites are
    accessible. I have disabled virus protection, and pop up blockers, and I
    have tried both Internet explorer and Mozilla firefox. I have downloaded
    latest versions of both these programs.I have reset security to lowest
    settings. The error message says can't find website. These sites are
    accessible on my laptop. I assume that some security measure, possibly some
    microsoft security update, has blocked it. Can someone help me reconnect to
    the library?

    Check DNS first.

    Go to www.dnsstuff.com and look up the A record of a website. Then do an
    nslookup and see if your local PC matches what dnsstuff found.

    If those match, then its time to start looking at your local DNS to see if
    it has them predefined for some reason, and if not, talk to whoever runs
    your forwarders (your ISP)

    Beyond that, any blocking could be done by ISA if you are SBS premium (you
    didnt mention) or a hardware filter on a firewall.

    Chris, Thank you very much for your input. Unfortunately, I am not
    sophisticated enough to take it and run with it. The TTL for nashville.gov
    is 86400 and the address is 170.190.30.54. When I run nslookup I get
    "Default server: 85.255.116.104-xbox.dedi.inhoster.com.
    Address:85.255.116.104."
    I don't understand what you mean by match

  6. Hello Frank

    Thank you for using Microsoft Online Support.

    What is the error that you see in Internet Explorer when you try to connect
    to the desired sites? Do you have ISA server 2004 installed on the server?
    Did this ever work for you? If so what changed in the environment? What
    does you network configuration look like?

    I look forward to hearing from you.

    Thank you
    Douglas Boyd
