Environment: Application Servers: Window 2003 standard, Sp2 (64 bit), Not in Domain .Net version Installed:  .Net Framework 3.5Sp1, .Net Framework 3.0, .Net Framework 2.0 Sp2

SQL Server 2005 Standard Edition SP3 Build 4266

Issue: Our web application based on .Net framework 2.0 is receiving the below error in event log while connecting to SQL 2005 instance. We are using the SQLOLE DB Provider to make the connection.  In he connection string we pass following information.

1.     Server IP

2.     Database Name

3.     User Id

4.     Password


Error message:

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The Local Security Authority cannot be contacted.


Temporary work around:

We are able to temporarily fix this issue by encrypting and decrypting web.config file.


Additional Notes:

Also we only encrypt app setting part of web config file with ASP.net default "DataProtectionConfigurationProvider".

 The following code is used in the application for establishing the connect

BCP Fails:The Local Security Authority cannot be contacted

We are launching BCP Process from a web page.

If the impersonate is set to false then we receive following error:

Login failed for user 'NT AUTHORITY\NETWORK SERVICE'.


If the impersonate is set to true then we receive following error:

SQLState = 08001, NativeError = -2146893052

Error = [Microsoft][SQL Server Native Client 10.0]SSL Provider: The Local Security Authority cannot be contacted

SQLState = 08001, NativeError = -2146893052

Error = [Microsoft][SQL Server Native Client 10.0]Client unable to establish connection.


Please note that we have to use impersonate = true option.


Thanks in advance.

OLE DB or ODBC error: Login failed for user 'NT AUTHORITY\LOCAL SERVICE'




I need help with a problem: When trying to process a analysis services project, I receive the following error message -


OLE DB error: OLE DB or ODBC error: Login failed for user 'NT AUTHORITY\LOCAL SERVICE'.; 28000; Cannot open database "DocumentDB" requested by the login. The login failed.; 42000.


I am using the service account for impersonation for the datasource. One suggestion I received from the data-access forum was to grant privileges to the local service for the database. I am not clear about the procedure to do that. Can someone please guide me through this? I am posting this question in thi

SharePoint Tutorial - Security

Security in SharePoint is comprised of users, groups and roles.

Users, Groups and Roles

A user account comes from the authentication system. For example, if Active Directory is used to authenticate then the user accounts will come from it.

There are two types of groups SharePoint uses: domain groups and SharePoint groups.

Local variable scoping in C#

In my previous post, Compiler-generated scopes for local variable declarations, I briefly touched on the issue of multiple meanings applied to the same name. In this post, I'll aim to flush out the compiler's rules with regards to binding names in their local scopes.

Compiler-generated scopes for local variable declarations

I was tasked with understanding and fixing a bug on error reporting with foreach iteration variables the other day, and it got me thinking about local variable scoping rules in C# in general. First, the bug.

Good Day all,

Having an issue with an outside user accessing my IIS7 box. I do not have this problem when running the website from my host machine. I found this post: Http://forums.asp.net/t/1371394.aspx. I assure you that this is not a solution because I am not storing any of my files on a network share. 

What do you think my approach should be. 

I already have read rights to IIS user to my BIN folder. 

Thanks for the help. 

XBAP Security


We have a small XBAP file upload app that we are having trouble deploying. We were getting security errors when we were pushing this application that we don't get when running in our development environments on our machines. We gave the XBAP app full permissions and still got errors. Then we created a personal certificate and were able to get this to work. But that means we have to load a client side certificate for each and every machine that wants to run this which is ridiculous. Does anyone have a solution for this?

Intranet Users Challenged When Using Windows Integrated Security


We've setup an intranet site using Windows Integrated Security. Its up and running and users can access it. However, they are being challenged with a login dialog for the server when they initially access the site.

Isn't is possible to configure the server so that the users aren't challenged AND are recognized as being already authenticated by Windows? We're trying to go with a seamless experience, whereby all they have to do is login to their machine like normal and then go from there.

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).

Changing from Local to WCF


I've been handed an application thats connection string implies a local host connection.

I want to make this connection a remote connection, to a database located on a Server.  I want the client and server to be able to communicate with one another remotely, instead of a local connection.

How does one create the Data Service, and establish end points to Server and Client?  Is it as simple as creating a contract (which I have limited knowledge on constructing), between the two locations, setting up the dataservice, security, and ratifying the 'connetions'?

A smidge of insight, please ;-)
