Is there any way to get OS version of remote machine in .Net(C#)? Using of WMI is not acceptable for me.

I have IP address of remote machine :) and administrator credentials

Answer 1

based on sgmoore answer with some usings

    public string GetOsVersion(string ipAddress)
    {
        using (var reg = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, ipAddress))
        using (var key = reg.OpenSubKey(@"Software\Microsoft\Windows NT\CurrentVersion\"))
        {
            return string.Format("Name:{0}, Version:{1}", key.GetValue("ProductName"), key.GetValue("CurrentVersion"));
        }
    }

Answer 2

If you have administrator credentials for the remote machine you could use PsExec to run a command remotely to get the OS version e.g.

CMD /c ver

You can write a wrapper to run PsExec in C# by using the Process class.
