In a domain environment this is really easy to adopt.

And this one will also ensure the uniquality. Only clients with certificates issued by you will be able to pass the authentication. If you want strong authentication from machine side, you can use certificate based authentication.

Thus it is not suitable for machine identification. MAC address is not guaranteed to be unique, and it can be changed. In 2011 there was a thread about this issue where someone, I think it was John Hawkinson, answered the question like this: var mySysName app.doScript ('do shell script 'hostname'', ScriptLanguage.APPLESCRIPTLANGUAGE) Awesome, this is exactly what I am after. than nothing will give you a solution working for every client. Hosts outside your L2 perimeters can not be queried for their MAC with common tools, so if you don't have access read their configuration remotely (WMI, SNMP.), or they are different dumb devices, or. If (SendARP(intAddress, 0, macAddr, ref macAddrLen) != 0) Uint macAddrLen = ( uint) macAddr.Length Int intAddress = BitConverter.ToInt32(address.GetAddressBytes(), 0) The only unique id you will be able to get is the IP address, but this will possibly not be unique as the user's machine might be NATed behind a router. Method 1 (IE for IE only and client side allows AcitiveX to run through platform: XP, SERVER03, 2000). It is not possible to get the MAC address from the client using JavaScript as this will pose a serious security risk. Public static string getMAC(IPAddress address) Several Methods of Obtaining Client IP Using JS. Public static extern int SendARP( int DestIP, int SrcIP, byte pMacAddr, ref uint PhyAddrLen)
