Access is Denied in XMLHTTP

[Ken Kolda]

We use the XMLHTTP component to fetch XML data from a remote server within
our product. But, on one client's machine, we're running into a problem
that we can easily reproduce in a trvial VBS script. The error we get is:

Error: Access is Denied
Code: 80070005
Source: msxml3.dll

The code that generates the error is really simple (and the error occurs on
the last line):

Dim HTTP
Set HTTP = CreateObject("MSXML2.XMLHTTP")

HTTP.Open "GET", "http://www.somecompany.com/somepage.asp", False
HTTP.SetRequestHeader "CustomHeader", "ABCDEFG"
HTTP.Send

This particular user is behind an authenticating proxy, but we have other
users with proxies who have had no problem (which goes along with my
understanding that the XMLHTTP component uses IE's proxy settings). I've
seen lots of discussion regarding this kind of error for the ServerXMLHTTP
component, but that's not the issue here.

If anyone has any ideas what the problem might be, I'd aprreciate your help.

Ken

I have run once into an access denied error with msxml3 that went away
when I switched to msxml4 (and used MSXML2.XMLHTTP.4.0). Not sure
whether it is an option for you (and whether it helps in this case).

Hi Martin,

OK, someone upgrades our server to SQL 2000 SP 3.0 and BOOOM... access denied / the server name or address cannot be resolved is here. The problem was fixed on one server, but not the other.

I am having the same error as Ken, even after upgrading to MSXML 4.0 SP2 and SQLXML 3.0 SP2 and SOAPXML 3.0... nothing seems to work. I even tried using the "proxycfg -d" to remove the proxy dependency AND rebooted the server (all advise I found in the Knowledge base article 289481 - INFO: You May Need to Run ProxyCfg Utility for ServerXMLHTTP to Work). I also came accross the readme for MSXML 4.0 SP2 Realease Notes where it mentions "Security tightened when posting data using the ServerXmlHttp Object". The recommended steps to use MMC do not make any sense in that I can NOT find a snap-in for the "Resultant Set of Policy" to choose when Adding Snap-In!!! ??

Finally, FYI... I did have the access denied error on another Windows 2000 Server for development testing, but after doing the "Proxycfg -d" and rebooting it works fine!

Now, if I can only make our live Server work properly!

Any assistance is greatly appreciated. As well, you may send emails to me at ***@hotmail.com

Sincerely,
Karl Engvold
