Why do I get error message ”Parser Error Message: Access is denied: Source Error: Line xxx : ”

The actual problem is because of the Microsoft Indexing Services which scans the Temporary ASP.NET Files and while doing so, the system puts a lock on the same.

To resolve this, the following steps need to be carried out:-

1. Start – Settings – Control Panel – Administrative Tools – Computer management.
2. Expand the services and applications node and select the Indexing service node.
3. Expand the Indexing Service Node and then select and expand the System Node.
4. Right click on Directories and select new directory. browse the path to the temporary asp.net files c:\winnt\microsoft.net\framework\v1.1.4322\.
5. Select the temporary asp.net files. give ok and then select the ‘NO’ in the Include in index radiobutton.
6. give ok and then stop and start the indexing service.
