Yes the user is set as Enabled,Global Administrator and Domain User checked. I am just getting the error while I am trying to Access CMSDesk or CMSSiteManager. Should I need to modify the web.config located on CMSSiteManager/CMSDesk folder .
CMSDesk/web.config :<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
<location path="accessdenied.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
</configuration>
CMSSiteManager/web.config :<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings/>
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</configuration>
