When you access a page after an AppDomain load, for example, when you modify the Bin directory or the Web.config file on computers running Microsoft Index Services, you may receive the following error message:
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Access is denied: 'mydll'.

If you right-click the page in the browser, and then click View Source, you see that the HTML source code reveals additional information, including the following call stack.

If you run Index Server (Cisvc.exe), then Index Server may rescan the Temporary ASP.NET Files directory while it requests a Microsoft ASP.NET page. Cisvc.exe then holds a lock on the Temporary ASP.NET Files directory for one to five minutes. The length of time of the lock depends on the size of the directory that causes the Aspnet_wp.exeprocess (or W3wp.exe process for applications that run on Microsoft Internet Information Services [IIS] 6.0) to not load the particular DLL.
If you do not use Index Server on the server, you can disable it. To do so, follow these steps:
| 1. | Click Start, and then click Services. |
| 2. | Locate Indexing Service from the list of services, and then click Indexing Service Properties from the subform. |
| 3. | On the General tab of the Indexing Service Properties dialog box, in the Startup type drop-down item list, click Disabled. |
| 4. | Click OK. |
If you use Index Server, you can exclude the Temporary ASP.NET Files directory from the folders that the Index Server scans. To do so, follow these steps:
| 1. | Click Start, point to All Programs, point to Administrative Tools, and then click Computer Management. |
| 2. | Expand the Services and Applications node, expand the Indexing Service node, and then expand the System node. |
| 3. | Right-click the Directories folder, point to New, and then click Directory from the subform to open the Add Directory dialog box. |
| 4. | Click Browse, and then locate the Temporary ASP.NET Files directory. You typically find the Temporary ASP.NET files in the following path: c:\<WINDIR>\Microsoft.NET\Framework\<Version Number>\Temporary ASP.NET Files Note<Version Number> is the version of .NET Framework installed on your computer. |
| 5. | Click No under the Include in Index? option buttons. |
| 6. | Click OK to close. |
| 7. | Close the Computer Management dialog box. |
| 8. | Restart the Indexing Services service. |
