when using FaxComExLib, my C# web application works great in Vista, but in Windows 2003 I get the following error:

Unable to cast COM object of type 'FAXCOMEXLib.FaxServerClass' to interface type 'FAXCOMEXLib.IFaxServer2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{571CED0F-5609-4F40-9176-547E3A72CA7C}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

in my web application's Bin folder if have Interop.FAXCOMEXLib.dll.

The version of c:\windows\system32\fxscomex.dll is 5.2.3790.3959.

Need you help.
