An "ASP.NET Framework Access denied" error is encountered when executing an ASP.NET page in K2.net Workspace. What could be the issue?
Typically, this error will occur when a Windows 2000 or Windows 2003 Server machine has been upgraded to a PDC, or when the default file level security has been modified by a user or software installed on the machine. When this error occurs, please note the folder in which the temp file is being created and change the security rights on the folder to allow IIS, the ASP.NET users, or everyone full access. ASP.NET uses temporary files when compiling ASP.NET pages during an IIS request. This is a common ASP.NET known issue in high security environments.

There were also instances where the error was caused by the absence of ASP.NET 1.1 registration with IIS. To register ASP.Net 1.1 into IIS, do the following:

1. Open a command prompt window
2. Run this command:
c:windowsMicrosoft.NetFrameworkv1.1.4322aspnet_regiis.exe -i
