ASPNET user does not have write access to Temporary ASP.NET Files

Question

When I run my Visual Studio 2008 ASP.NET project (start without Debugging) on my XP Professional box, I get the following error:

System.Web.HttpException: The current identity (machinename\ASPNET) does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.

How do I resolve this?

Answer 1

Have you tried, the aspnet_regiis exe in the framework folder?

Answer 2

Make sure the ASPNET user has permission to write to that folder. Right click on the folder, Properties, Security tab.

Answer 3

Either grant that user the level of access to that directory, or change the identity that the application's application pool runs under - in IIS Manager, determine what App Pool is used to run your application, then in the App Pool section of IIS Manager, look at the properties for that pool - the tab you want is "Identity" I think (this is off the top of my head).

You can set it to another user account - for example, Crystal Reports .Net requires update and delete access to C:\Temp - so we have a "webmaster" user, with administrator access, and use that identity for those applications.

Answer 4

You can try to fix it using the automated regiis utility aspnet_regiis.ext available in c:\windows\microsoft.net\framework\v2.0.50727

Otherwise just manually add the needed file permissions as noted in the error.

Answer 5

you can right click the Visual Studio & select run as administrator.
