Problem with Web Service and COM Object

[Julián]

Hi:

I have a Web Service developed in Vb.Net. One of its methods does a call to
a COM object developed in Visual Fox. When I run my application in
production, I get the error:
"Creating an instance of the COM component with CLSID
{01DFFCBA-0138-4836-BD6F-CB17-CE94E2C5} from the IClassFactory failed due to
the following error: 80004005"
The user ASPNET has "Read" permissions in the folder where is the COM
object.
What more things should I check ?

Regards.
