DCOM function

Hi, I have this problem. I'm using COM function on local PC, but I need to run Excel on another PC. PHP give me this error: Warning: Unable to obtain IDispatch interface for CLSID {00024500-0000-0000-C000-000000000046}: Acces is denied. in C:\Inetpub\wwwroot\somescript.php on line 8 line 8 is like: $Instance = new COM("Excel.Application", "remote_server_address"); DCOM is enabled in php.ini. PC with PHP is running on WinNT 4 srv, IIS4 and ISAPI PHP4, second PC is on Win2000 Prof., Office2000. Both computers are logged in the same domain as Administrator, I also tried run IIS under Administrator account. Still the same result. On local computer with COM (i.e. new COM command without the second parameter) it works fine - as local I tried both PCs. Anyone have an idea? Thanks. deep
