How would you do it?

[SpookMeister]

Here's the scenario:

I have a bunch of PC's all either Win2K or XP sitting on a particular subnet. However they are not alone on the subnet, it also contains a few other network devices even a few PC's that I specifically DO NOT want to perform actions on. Fortunately, all of the PC's I desire to address follow a unique naming convention IE (DW25, DW104, DW152, etc.)

I want each of my target PCs to execute a file located at "\\server\share\executable.exe"

I think I have a grip on the remote execution side of it (psexec from sysinternals) but I'm looking for ideas on the subnet scanning / identifying my target pcs side. Or perhaps you have a better method entirely... either way, the help is appreciated.

Oh, if your wondering why I didnt go with a login script in an active directory group policy.... I tried it, but ran into issues with the program running twice per login. Which caused other issues... blah blah blah.

for $i = 1 to 152 ; or whatever topend you want

if ping DW & $i then run(psexec DW & $i.....

next
