Cant access msmdpump.dll setup in IIS from a box other than localhost

Question

I configured access to SQL Analysis Services via IIS on one of my machines, as per the following instructions:
http://mglaser.bloggingabout.net/2008/08/15/configuring-http-access-to-sql-server-2008-analysis-services-on-microsoft-windows-server-2008/
I tested using Excel on the same machine and it works fine. I access using the following url (I can access without using localhost on that machine):
http://10.3.29.79/OLAP/msmdpump.dll
But when I try it from any other machine on the same network using Excel it does not work. Now I know you cant use IE for testing but I just watned to see if I could resolve to even the error you normally get in IE.  Something along the lines of:
- <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
- <soap:Body>
- <soap:Fault xmlns="http://schemas.xmlsoap.org/soap/envelope/">
<faultcode>XMLAnalysisError.0xc10e0002</faultcode>
<faultstring>Parser: The syntax for 'GET' is incorrect.</faultstring>
- <detail>
<Warning WarningCode="1090584599" Description="The 'Invariant Language' locale for UI is not supported." Source="Unknown" HelpFile="" />
<Error ErrorCode="3238920194" Description="Parser: The syntax for 'GET' is incorrect." Source="Unknown" HelpFile="" />
</detail>
</soap:Fault>
</soap:Body>
</soap:Envelope>
But all I get when I access from other machines is an error 500, internal server error.  I'm not worried about it not working in IE as I know it cant, but I do think there's an issue accessing from any box except the host. 
Thanks for any advice!

Hi Rmccabe,
Try Turning off the Friendly errors in IE and then launch this URL to find the exact error.
Try  changing the Authentication Mode in IIS XMLA Virtual Directory to Anonymous Aurthentication and try launching the URl.
you can even try connecting the Analysis Server With SSMS by giving the XMLA URL  "http://10.3.29.79/OLAP/msmdpump.dll"
in the Server Name Text box.
Try Disabling Firewall- It it works then Add the Proper port no to get rid of this issue.
Since you are able to access the cube with the Local Server (Localhost). These are the common reasons for these error.
