Knowledge Base FAQ Item #3500015


Q3500015: In your ASP sample I can't see my Windows' Telephony Devices (for instance, my 'Standard 9600 bps Modem'). In all other samples, they are listed. Please advise.

On the webserver, the IUSR_<computername> credentials are used for all SMS operations. The IUSR_<computername> is only member of the Guests group by default; it doesn't have sufficient permissions to query the Windows Telephony Devices. By making the IUSR_<computername> account member of the Local Administrators group, you will be able to see all Windows Telephony Devices.
