Network Level Authentication completes user authentication before you establish a remote desktop connection and the logon screen appears. This is a more secure authentication method that can help protect the remote computer from malicious users and malicious software. The advantages of Network Level Authentication are:.
I was pleasantly surprised to find the entries already existed in my registry. Perhaps I did this a year or two back and just forgot. I don't know much about computers, but was able to follow these steps and it works great! Great tutorial. Great tip! Solved in moments. Keep up the great work! Cheers Anthony.

Patrick Green. Main Areas of Contribution:. When Bob moves throughout the company's offices, sometimes he can't get network access; for example, in the warehouse there is no wireless network access. Even so, Bob needs to be able to answer e-mail messages and add reports to the system on fixes he has made. Bob's e-mail application should download and upload messages between the mail server and his laptop whenever Bob is connected, but a message that hasn't completely transferred when connectivity disappears should not be lost.
The e-mail application needs to cope with aborted message transfers. Similarly, Bob's issue reporting tool connects to a database on a company server.
The database contains all the records of technical issues and fixes made by Bob and his colleagues on the tech-support team. This system is the way most of Bob's work is routed to him. He collects an open issue from the issue reporting tool and gets the details from the database; he then goes to the suspected location of the fault to fix it. When Bob leaves a location that has network connectivity, the reporting application keeps the last fifty records Bob was looking at in a local cache.
Bob can view and update these records locally on his laptop. The next time the application detects a network connection, it attempts to synchronize all of Bob's changes with the database. If the network connection drops out, any records that didn't get fully synchronized are cached until a connection is detected again. The second situation is that of Jenny, who works for an insurance company and spends most of her time out of the office, usually only popping into the office for Monday morning meetings.
She sells insurance and visits claim sites to help her customers make claim reports. Jenny has a Tablet PC and is more often disconnected than she is connected.
Jenny relies on two applications for her day to day work: an e-mail application, and an application that contains all the forms her insurance company uses. The e-mail application will connect and upload or download e-mail messages whenever it detects an internet connection. The company's forms application will only connect to the company server when Jenny is connected through a VPN or directly on the company network. In this second situation, the insurance company application detects when it has a connection to a known network before attempting to synchronize the forms Jenny has filled in for her customers.
The e-mail application, on the other hand, is less particular, and as soon as the application detects any network connection, it attempts to synchronize Jenny's e-mail with the company mail server. An application that is only sometimes connected should attempt to provide the user with continuous operation of the application as the mobile PC connects and disconnects from networks. Features of the application that require network access could be hidden from the user or work on a local cache of the data.
Either way, the network features should not degrade the user's experience with the application. As a first step to providing seamless network support in your application, it is useful to know which networks the application can currently access.
NET Framework does not provide this information inherently. In order to get this information, your code must call native Win32 methods. Version 2 of the Microsoft Windows Sockets Library that is shipped with the Win32 Platform SDK has a number of functions that you can use to detect the currently connected networks.
They are:. Before these methods can be successfully invoked, you must make a call to the WSAStartup method to initialize the process for using the Windows Sockets Library.
You should also remember to call the WSACleanup method when you have finished using the library. You can create a simple loop to iterate through the currently available networks using these functions. The pseudo code looks like this:. In the example code that follows, you can see these structures defined as a C classes; this is done because a C class is always passed by reference, making the call to the methods simpler.
Note that in the WSAStartup method, the second parameter doesn't have to be marked as an [out] parameter or use the ref keyword. The second parameter is simply an instance of a WSAData class:.
With these methods defined, you call them as shown in the following example code.
