When you try to create a component or access a method, you may receive the following error message: Or you may receive the following error message from Active Server Pages (ASP): These errors mean that there are insufficient permissions to access a file.

To find the dynamic-link library (DLL) file on which the caller has insufficient permissions, you can trace all access to all files with the Filemon tool. Similarly, you can trace all calls that go to the registry with the Regmon tool. You can download both of these tools from the following Sysinternals location:

Steps to Capture Permission Issues

1.	Start Filemon. The tool immediately scrolls and sends a lot of information about which process is accessing which file. It also displays the results of those interactions.
2.	Reproduce the error, and click the magnifying glass on the toolbar to tell Filemon to stop logging.
3.	Save the results to a log file.
4.	In Microsoft Excel, open the log as a text file. In the wizard about how to convert the text file into a spreadsheet, click Finish.
5.	In Excel, on the Data menu, click Filter, and then click AutoFilter to filter the results.
6.	On the Results column, click Permission Denied.

In the Process column, you can see which process tried to access the file; in the Path column, you can see which file received the "Permission denied" error. You can reset the NTFS permissions on this file to resolve the problem.
