Can anyone help me understand what this error message means. It has started to appear in my Visual Studio environment.

I save my work and run my code again and when the 1st web form loads all is well.
I do it again and I get this message.
It is intermittent but very very annoying.



Compiler Error Message: BC31011: Unable to load referenced library 'c:\windows\microsoft.net\framework\v1.1.4322\temporary asp.net files\selfservice\db8553d0\167d2047\assembly\dl2\0d745bf6\0060a90f_c6f2c201\interop.activeds.dll': Access is denied.

Thanks,
Sam.
