SYMPTOMS
When you change any setting on the Settings.aspx page in Microsoft Office Live Meeting 2005 or in Microsoft Office Live Meeting 2007, the following error message is logged in the LMPortal event log:

Exception_1034: The 'HttpPostXML' call returned a fault (Fault Code=Client.Authorization.NotAdministrator, Fault String=You must be an administrator to perform the operation GetUser, URL=https://www.livemeeting.com/cc/_XML/contoso/xml/4.0)



CAUSE
This problem occurs because the Live Meeting Administrator account that is used by LMPortal does not encode any special XML characters, or the ampersand (&) character, correctly in XML API requests that are sent to the Live Meeting service.

When you change any setting on the Settings.aspx page, all the configuration fields on the page are written to the configuration details. If the password for the Live Meeting Administrator account is left blank, a null password is written to the configuration details. Therefore, a null password generates the error.



RESOLUTION
To resolve this problem, install the latest version of Microsoft Office Live Meeting Service Portal. To do this, visit the following Microsoft Web site:

WORKAROUND
To work around this problem, always fill in the password field when you make any changes on the Settings.aspx page. Make sure that you do not include any special XML characters, or the ampersand (&) character, in the password.
