About Chris Expertise I can answer pretty much any question relating to VB.NET and its use in a Windows environment. I can also handle most questions using C#. I specialize in ASP.NET web development and MSSQL database access, but have some stale knowledge of the old ASP - I'd prefer to avoid questions about it.
Experience I have over 5 years of industry experience using VB.NET and other .NET technologies for web and database development.
Education/Credentials I have some college education, but does it really matter in this field of work?

I had no idea what is going on and I had tried to fix it but fail.
Can you please help me?
Thanks & Regards,

Answer Well, the error message actually says exactly what is going on:
The current identity (CYK016-03\ASPNET) does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.
ASP.Net applications run under a worker process, and this in turn must be run under a user account. For security reasons, Microsoft won't let this run as the SYSTEM account, because it has full control of your system. Instead, it runs as a user called ASPNET. CYK016-03 is apparantly your computer name. And what the error is saying is that this ASPNET user on your computer does not have access to write to the folder C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\. This is where ASP.Net generates its temporary files (mostly assembly DLL files), and the worker process user account must have write access to this folder for ASP.Net to launch.
So, log onto your computer as Administrator and open Windows Explorer. Browse to C:\WINDOWS\Microsoft.Net\Framework\v2.0.50727\. Right-click the "Temporary ASP.NET Files" folder and pick Properties. Go to the Security tab, and click Add. Type in CYK016-03\ASPNET and click OK. Then find the ASPNET user in the list, and Grant it Full Control. Click OK. Then, go to Control Panel -> Administrative Tools -> Services, find IIS Admin Service in the list, right-click it and pick Restart.
