Determining closest server

I am trying to determine the "closest" server to any given user and then map a drive to that server. I was going to shell out the ping command to ping each server and then get the response time from each server and then connect to that server, but I'm not exactly sure what would be the most efficient way to accomplish this.

Closest as in response time. This drive will never be mapped to server that is authenticating logons.

We defined the user's home share on the local F/P server. Each F/P server has idential common directories and shares. The logon script extracts the the server portion of the users home share property and maps all standard drives to that server.

Ping may not be the most reliable in all cases, but in the case it should work fine. We're talking about 1000's of users accross the country connecting to only 1 out of 5 or 6 servers dedicated for this specific application. The differences in response time will be drastic depending on the user's location. I just need a way to efficiently gather the ping stats and map to the server with the fastest response time.

I think I'd go for TRACERT hops too, as mentioned in my first post, unless the connections to the different servers are vastly different like T1 to SERVER1, DSL to SERVER2, Frame Relay to SERVER3.
However, all the tools necessary can already be found in the UDF forum, like PING UDFs, WSHPIPE, and so on.

I just updated WSHPing() to return the average ping time to the target.
http://www.kixtart.org/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=12&t=000219#000000
$p=WSHPing("server3",5)
? $p[0]
? $p[1]
? $p[2]
so now you can WSHPing() your list of servers and find out ping time... run it through a sort, and you will have your victim.
