ISS can lock the ASP.net Temp folder files

  • Artigo

 

Problem:

If you're browsing to an asp.net page and your browser reports "Sever Error in '/' Application." and "The current identity... ASPNET does not have write access to 'c:Windows\microsoft.net\framework\v2.0.50727\Temporary ASP.net files', you might naturally think of adjusting NTFS permissions for the ASPNet account or running aspnet_regiis -ga in the attempt to correct the problem.

Possible solution:  

Try stopping any and every service that has anything to do with either Blackice and/or ISS (that's ISS, not IIS). Particulary look for the "ISS Buffer Overflow Exploit Prevention" service. Stop it. Restart IIS. Test asp.net functionality.
