I have an Windows 7 machine with Office 2010 (32 bit) installed.
I have installed the 32-bit MDS Add-in for Excel.
When I connect to the MDS I get the following error:
The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate, NTLM'.
Additional information: The remote server returned an error: (401) Unauthorized. (System).
Please note that a work colleague can connect perfectly but she is on Windows XP.
Windows Authentication is not enabled for the Master Data Manager Web application in Internet Information Services (IIS).
For more detail information, please refer to the article below:
