Hi Adam,

Thanks for the reply,
Here it takes two points as input means do we need to check this for every feature in the layer(point layer).

What about incase of Line or Polygon feature class(layer). How can we find it out?

You can create (with 10 version) a rest soe

and on server work with spatial index (every square have list of ids contained) then you try nearest from ids in square.

You could publish a geoprocessing toolbox using the "Generate Near Table" tool. This worked for us but required an upgrade to ArcGIS Server Advanced Edition.
