Unable to Serialize.

[Nachi]

I have installed SQL Server 2000 with VS 2005 - did not install
SqlExpress\Sql 2005. I have a remote Sql Server Instance locally. The
normal application connectes to this Sql Server. When I run Asp.Net
Configuration from VS 2005 it gives this error.

I have removed 'LocalSqlServer' in machine.Config and added in
web.config as following.



<system.web>

<connectionStrings>

<add name="LocalSqlServer" connectionString="Data
Source=DSRD-TESTSERVER;Initial Catalog=ASPSEC;Integrated Security=True"



providerName="System.Data.SqlClient" />

</connectionStrings>



Server Error in '/asp.netwebadminfiles' Application.

Unable to serialize the session state. In 'StateServer' and 'SQLServer'
mode, ASP.NET will serialize the session state objects, and as a result
non-serializable objects or MarshalByRef objects are not permitted. The
same restriction applies if similar serialization is done by the custom
session state store in 'Custom' mode.

Please help

My web.config

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging.
Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols
(.pdb information)
into the compiled page. Because this creates a larger file
that executes
more slowly, you should set this value to true only when
debugging and to
false at all other times. For more information, refer to the
documentation about
debugging ASP.NET files.

<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom
error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.

"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users
not running
on the local Web server. This setting is recommended for
security purposes, so
that you do not display application detail information to
remote clients.

<!-- AUTHENTICATION
This section sets the authentication policies of the
application. Possible modes are "Windows",
"Forms", "Passport" and "None"

"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or
Integrated Windows) according to
its settings for the application. Anonymous access must be
disabled in IIS.
"Forms" You provide a custom form (Web page) for users to
enter their credentials, and then
you authenticate them in your application. A user credential
token is stored in a cookie.
"Passport" Authentication is performed via a centralized
authentication service provided
by Microsoft that offers a single logon and core profile
services for member sites.
