Description:
------------
I'm not able to instantiate an object of my COM interface under Windows 2003 Server. I'm using the following code:

$obj = new COM(" <ProgID> ");

Under all other windows oporationg system it works fine, but not with Windows 2003 Server.

The error message is:

Warning: (null)(): Unable to obtain IDispatch interface for CLSID {C9E9F131-B9B5-4779-8267-D67B50EEBC20}: The server process could not be started because the configured identity is incorrect. Check the username and password. in c:\program files\apache group\apache\htdocs\test.php on line 7

Surprinsingly $shell= &new COM('WScript.Shell') for example makes no problems. So what is wrong with my COM interface?

I'm using PHP with apache 1.3.26 as a module.

Thanks in advance
Chris

No, it's the same behaviour. The only difference is that the request takes some seconds now. Afterwards the error "The page cannot be displayed" appears in the browser. In the error.log file there's an entry with the error described below (Unable to obtain IDispatch interface for CLSID ...).

I tested it with PHP 5.0.3 on Windows 2003 Server and it's the same error:

Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `<...>': The server process could not be started because the configured identity is incorrect. Check the username and password. ' in c:\program files\apache group\Apache\htdocs\test.php:7 Stack trace: #0 c:\program files\apache group\Apache\htdocs\test.php(7): com->com('<...>') #1 {main} thrown in c:\program files\apache group\Apache\htdocs\test.php on line 7

So it really seems to be a bug in conjunction with Windows 2003 Server.

One more hint:
If i use dcomcnfg on my Windows 2003 Server to specify the corresponding application to run on another computer (Windows XP Prof), everything works fine. Unfortunately i cannot use this configuration...

Any idea?

You need to set up the access permissions/identity correctly.
This is not a PHP bug.
Consult the Microsoft Knowledge-base for help on this issue.
