Routine Description:

    If the IWAM account has been modified, it is necessary to update the
    the out of process com+ applications with the correct account
    information. This routine will collect all the com+ applications and
    reset the activation information.

Arguments:

    pcCom               - metabase object
    szWamUserName       - the new user name
    szWamUserPass       - the new user password

Note:

    This routine is a royal pain in the butt. I take back
    all the good things I may have said about com automation.

Return Value:
    
    HRESULT             - Return value from failed API call
                        - E_OUTOFMEMORY
                        - S_OK - everything worked
                        - S_FALSE - encountered a non-fatal error, unable
                          to reset at least one application.
