Hi Calvinx,

This error mostly belongs to permission error, for this error we have mutiple solutions as per situation

1. 
   

   Put the impersonate=false in web.config file.

   
   
2. 
   

   If you want to put the impersonate = true in that case you need to provide the read/write permission to impersonate user on "C:\Documents and Settings\server name\ASPNET" folder or through process monitor utility you can check which file don't have sufficient
   permission.

   
   
3. 
   

   If you have windows server 2008 then you will not found the ASPNET folder and still want impersonate=true then you need to change the configuration in IIS 7.5/7.0.

   
   

Go to IIS -> select your application pool -> Advanced Setting -> Process Model ->Identity=ApplicationPoolIdentity

Go to IIS -> select your application pool -> Advanced Setting -> Load User Profile = False
