Question

I have an ASP.net Application that runs on the internal network (well, actually it’s running on Sharepoint 2007).

I just wonder:

Can I somehow retrieve the name of the PC the Client is using? I would have access to Active Directory if that helps. The thing is, people use multiple PCs. So, I cannot use any manual/static mapping.

If possible, I do not want to use any client-side (read: JavaScript) code, but if it cannot be done server-side, JavaScript would be OK as well. ActiveX is absolutely out of question.

Answer 1

System.Web.HttpRequest.UserHostname as suggested in this answer just returns the IP 🙁

But I just found this:

System.Net.Dns.GetHostEntry(Page.Request.UserHostAddress).HostName 

That only works if there is actually a DNS Server to resolve the name, which is the case for my network.
