Hemos detectado el siguiente problema tras instalar Plesk 9.3 sobre Windows Server 2008 R2.
Server Error in '/mssql' Application.
--------------------------------------------------------------------------------
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access is
denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
ASP.NET is not authorized to access the requested resource. Consider
granting access rights to the resource to the ASP.NET request
identity. ASP.NET has a base process identity (typically
{MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if
the application is not impersonating. If the application is
impersonating via , the identity will be
the anonymous user (typically IUSR_MACHINENAME) or the authenticated
request user.
To grant ASP.NET access to a file, right-click the file in Explorer,
choose "Properties" and select the Security tab. Click "Add" to add
the appropriate user or group. Highlight the ASP.NET account, and
check the boxes for the desired access.

El error se podía reproducir al tratar de ejecutar una aplicación ASP.NET desde Plesk, en nuestro caso al lanzar el administrador web para bases de datos SQL Server ASP.NET Enterprise Manager o MyLittleAdmin que se ejecutan desde Plesk.
Si tratamos de corregir el error desde la herramienta Plesk Reconfigurator no solucionaremos el problema debido a que los permisos necesarios no estan añadidos. Por ello, tendremos que hacerlo a mano.
Lo único que tenemos que hacer es editar el archivo DiskSecurity.xml que encontraremos en la carpeta %PLESK_DIR%etcDiskSecurity y añadirle el siguiente contenido dentro del tag Entries:
<!-- Permisos a Assembly para ASP.NET Enterprise manager -->
<Entry AccounType="1" Account="Psacln" Path="C:Windowsassembly" AceFlags="FilesOnly" AccessMask="Read" EntryFlags="0x0" />
Finalmente hay que ejecutar el siguiente comando para que se apliquen los cambios en los permisos:
"%plesk_bin%applysecurity" --apply
