Hi, I need to get a list of the computers in my WorkGroup LAN, with its names
in a similar way you get the available Drives from a PC with
DriveInfo.GetDrives(). Is there a managed class that provide this, if not,
coudl you provide me some guiadance with unmanaged APIs or wrappers.

Hi Fernik,
As for looping network resources in local network, there are several means
such as RAW network API, wmi or ADSI:
here are some web threads discussing on this, you can have look to see
whether they help some:
API approach:

#Using Network Functions in Visual C#.NET (Part II - Group Functions)

ADSI approach:

Hey Steven,
Thanks for your resourceful post, I did managed to build my own
NetworkBrowser class that enumerates the Domain computers and its shares,
however I have another question. Some shares require credentials in order to
access/enumerate them and they throw an UnauthorizedExcepcion, is there any
way to invoke the OS dialog that Windows Explorer displays when it need to
request credentials for a network resource, if not which APIs
managed/unmanaged are available to perform that impersonation.

Hi Fernik,
As for the protected network share, I'm afraid popup the login dialog
(interactively) is not quite doable here. The reasonable way is to run your
application(at least the thread) under a proper domain account(the
impersonate as you mentioned). Here is a kb article mentioned how to call
API to enstablish a certain account's logon session and impersonate in
NET( the article is for ASP.NET, but the code in it also fits deskop
application):
#How to implement impersonation in an ASP.NET application
http://support.microsoft.com/kb/306158/en-us
Hope this helps also.
