User authentication within a corporate network

[kretinga]

Hi,

Is there another way of authenticating a user rather than using "runas" command when calling "System exe" within LabVIEW? By authenticating, I mean, checking if a user typed valid windows login password.

When calling "runas", an application to be run needs to be specified. Therefore, there would be another application appearing upon successful password. However, the intention is to check the password only and not to open another app.I wonder is there another way of doing this? Is there a pre-developed LabVIEW library?

Thanks in advance

Here is a simple .Net implementation.

aptivo's, thanks for the help.  This has been an excellent solution to my problem. 

Before, I close I wonder is there anyone else would be having a suggestion on how to implement without .net? I know I might sound a bit too fuzzy, I just would like to reduce dependency .net if possible.
