"...IP addresses that are not allowed to access the Web site..."

Posted on 2006-05-08

When I try to access (from the internet) a company intranet hosted on Windows 2003 SBS I get this error:
"The Web server you are attempting to reach has a list of IP addresses that are not allowed to access the Web site....."

It is a server I have just installed last week and I did not put togehter any black list. (???)
Where I can find this list and how can I edit it?
Thank you!

    I have followed the advise on the link above and the only think i got is more headic.
    I must have done something wrong, bacause now I don't have a site at all.
    I can connect ot the default page but not to the "companyweb" and not to
    The last one give me more of the headics beacause now, nobody can use the webmail anymore.
    I have looked at the ISS config. and I can't see anything wrong, so far.
    Is any truc I can use get back to "yesterday"? I don't have a back-up (yet) of the OS and the ISS.

    Okay... there were two things listed there... one of them was to change your browser settings on the computer you are trying to access the companyweb.  You should not have done anything on the server to check that.

    This is the quote from the posting:

    "you may check if Internet Explorer of the problematic client is
    configured to use some Proxy servers. Please make sure that the "Bypass
    proxy for local addresses" internet options, is checked and is working

    Then, if that didn't correct the problem then there was a 5 step process to change the security settings on the default web site:

    1. Open the IIS console
    2. Open the Default Website's properties
    3. Click the Directory Security tab.
    4. Click the Edit button next to the IP Address and Domain Name Restrictions heading.
    5. Choose Granted access.

    If this is all you did, there shouldn't be any problem... but I suspect that you did more?  If so, please tell me what you did.  Because if you were doing all of this without a backup then you're going to have to figure out what you did and undo it.

    I have granted access to all computers on the default site and on the "companyweb" site then restart the two sites.
    After this I couldn't acces the "companyweb" and the "exchange" (webmail) anymore.
    I must find out if somebody else did something on the server without me knowing.
    A few days a go everything was just fine and I did not tested again before doing the chnanges I told you about.
    It is unfortunatly that I don't have a back-up (I usually do :(
    If i have a look at the path of the two sites and I check the folders it seems that files are missing.
    I will be thursday on site over there and I will have a "closer look" at this server.
    I hate headics...
    For now, thanks!
    I will talk to you later...

    First take two aspirin.  The headache will go away.

    If you've made changes but haven't rerun the Configure Email and Internet Connection Wizard, I'd suggest that you give that a try.  It can't really hurt anything at this point and could possible get your OWA and Companyweb back up and running.

    But you should not have changed the permissions settings for companyweb.  They are set the proper way by the wizard.
