I know this topic is discussed several times here but I read them and I don't believe they apply to my scenario. I added the following to my web.config:
<location path="Admin/default.aspx">
<system.web>
<authorization>
<allow roles="Customer Service Admin" />
<deny users="*"/>
</authorization>
And I started getting the error. I looked at the other SO posts on this and I found another web.config higher up in the Account subfolder but I deleted it. There are no other web.config files. I have done the other things like deleting the obj file but I keep getting this error. I am running i IIS Express locally. What else could it be?
