ok, i just ran this code to get more informtion on the @error being thrown.

code:

seterror("-2147024843")
? @error
? @serror
function seterror($a)
	exit($a)
endfunction

and i get the following.

-2147024843
The network path was not found.


As for needing ADSI in the remote computer....Looks like i may be wrong!
