PHP Component Object Model “Access is denied”

问题

My development environment is PHP 5.3, IIS 7.5, and Window7 Home. I am developing a prototype application, which requires the PHP function imagewindowgrab(). This function requires calling the Windows Component Object Model (COM).

My single line of code was this:


$browser = new COM("InternetExplorer.Application") or die("Unable to instantiate IE");

It produced the following error:


Fatal error: Uncaught exception 'com_exception' with message 
'Failed to create COM object `InternetExplorer.Application': Access is denied. ' 
in C:\inetpub\wwwroot\trial.php:8 Stack trace: #0 C:\inetpub\wwwroot\trial.php(8): com->com('InternetExplore...') #1 {main} thrown 
in C:\inetpub\wwwroot\trial.php on line 8

After searching for hours, trolling through .NET forums, and finding good resources:

http://forums.asp.net/t/1680634.aspx/1
http://learn.iis.net/page.aspx/624/application-pool-identities/

What finally worked for me was following the instructions outlined in the answer to this SO question:
Accessing Office Word object model through asp.net results in "failed due to the following error: 80070005 Access is denied."

AND following up those instructions with the following:

On the command line enter DCOMCNFG
Click right on Console Root > Component Service > Computers > My Computer and select Properties
On the tab COM Security > Access Permissions click on Edit Default and add the user (e.g. IIS_IUSRS) or service
Check allow local access

This appears to have taken care of my Access Permission problems with the COM framework from PHP.
