6.2 ASP.NET temporary folder permissions
If your MyID web service user does not have permissions to the .NET framework folder, you may see an error similar to the following:
The current identity "mydomain\myiisuser" does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.
To grant access to the web service user, run the aspnet_regiis command in the .NET folder mentioned in the error message:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727> aspnet_regiis -ga "mydomain\myuser"
Replace "mydomain\myuser" with your system's MyID web service user.
