How do I set my server up to let it contact specific URL?

Posted on 2005-05-02

I have a site that needs to contact to a merchant account for credit card transactions.  Everything had been working fine, but for some reason this morning I started to get a:

WinHttp.WinHttpRequest error '80072ee7'

The server name or address could not be resolved.

After I log on I notice that I can not get any url to be accessed with my web browser including the merchant url.  I have tried the same url on computers that are not in the same network with no trouble.  The site it's self is working fine.  It is only with the merchant connection that I am having the issue.

I would like to try and see if I just need to allow the server to connect to the outside sevrver but am not sure how I set that up.

The odd thing about this issue is I have not touched any of my web server for a couple months now with now.

Also should there be other things I sould check that I am not thinking of.

Thank you.

    This looks like a change done by the merchant server, either DNS or connectivity... I'd contact them first to see if they changed anything. Do I understand correctly, you can't contact their server at all from within your network? In that case it would have to be on their side.

    softplus.. the site is working, just not from his network.. "I have tried the same url on computers that are not in the same network with no trouble"
    he said he can't get to any site at all which means his network isn't working
    if you allow ICMP, can you ping anything such as or
    which DNS server are you using? can you ping it?
    can you ping your gateway?
