How to retrieve workstation hostname

Please can anyone tell me how to get the hostname of the client workstation
from the service. I've been trying to work with
System.ServiceModel.OperationContext.Current but I haven't got it yet.

Thanks

I'm using anonymous authentication on net.tcp. Is there a way to get the
ipaddress or hostname despite this. Logically, the service must have a
network address to route the return packets to so ...

Try
if (OperationContext.Current.Channel.RemoteAddress.Uri.IsAbsoluteUri)

ret =
OperationContext.Current.Channel.RemoteAddress.Uri.AbsoluteUri.ToString();

else

ret = OperationContext.Current.Channel.RemoteAddress.Uri.ToString();

Thanks Arkady,

Apparently the RemoteAddress uri is an AnonymousUri so this does not work.
After some research, I found out it is not possible to get the client's
address. Many people have thrashed MS for this but the official position on
MSDN and blogs is that this is necessary to be able to support NAT,
firewall, proxies, etc. It seems the only way to get the hostname or IP
address is for the client to send it deliberately to the service. Thanks
anyway. Perhaps MS would like to do something about this before finalizing
..Net 3.5.

That work for me as a charm but not with AnonymousUri.
The other way to use Native ( windows ) api : GetTcpTable()
