Access CLIENTNAME

At the risk of getting my head bitten off I ask this again, as I am not getting any help anywhere. I'm running a PHP system that relies on knowing the location of the terminal to handle a lot of '911' (999) type things. I know that REMOTE_ADDR can not be relied on, but with fixed IP addresses on a local network it works fine. However I now have a customer who has a Terminal Server thin client network, and REMOTE_ADDR only reports the server address. In order to restore the facilities I need to gain access to the CLIENTNAME environmental variable from the browser and return it to PHP. I've already got the simple bodge - they type it on on login - which is simply a joke when coming to use the system. I have a TS logon batch file which copies the CLIENTNAME variable to a file from which it could be accessed. BUT I have yet to find any way to pass the information. Can anybody kick me in the right direction, or do I have to stick with a drop down list in the logon box and expect everybody to know where they are? Surely VOIP is going to run into this problem soon isn't it? (Not that I can see how TS can actually handle the microphone and camera anyway ;) ) -- Lester Caine ----------------------------- L.S.Caine Electronic Services
