ADECCO is the domain name. Interesting that @serror returned by me

"Error (317 / 13D) while retrieving error information for 8007203A"

is different to the one returned by Bryce
"The network path was not found."

Certainly $dom = GetObject("WinNT://ADECCO")
works and if I loop through the objects returned I get lots of stuff back.

I'm very perplexed. Is the solution to install ADSI on all computers or all network servers or just DCs and BDCs ?
