Hello,

 There's a network. And there are a server (MS Windows Server 2003) with shared folders on it and lots of user machines (WinXP). If user makes any changes in the folder, the server should make a log. Everything looks like easy using FileSystemWatcher. But the problem appears, when it comes to getting IP of the machine, on which that change was made. I did enable security auditing on each computer but it skips some events (like creating a "New Folder") and it also makes redundant events in other cases (if you delete a file, you'll have more than 3 records). Everything I need is to create a record like "date/time event(create/delete/renamed) path IP(who did)" in a file.
 

Well...  in the context of an ASP.NET application, all changes would actually be made by the web server.

But it appears that you are actually asking your question in the context of a windows application. Since these forums are for ASP.NET (web sites / web applications), not windows applications, you might try your question at the MSDN Forums which deals with Windows Applications written for .NET.
