Updation of exe on netwrok PC

Question

Dear all,

I have developed windows application using .net framework 2.0 & sql 2005 as backend.

This application is installed on network PC'. Only one PC has sql server 2005 installed & all netwotk pc's are accessing that PC.

My issue:
When there is some change in application the i have to go on every pc & update the exe.

Is there is any simple way, If i have update the exe at server PC then automatically network pc's exe should be updated.
Or
there is something some popup should be come on network pc's that new version of software is come. Plz upgrade ur software.

Is it possible, Plz give some suggestion.
