HI Bryce.
I received grate help from you.
Do you believe that I spend about 3 weeks working in this task, I tried first Instsrv.exe and then SMS create service function, then finally Rservice.exe all of these tolls couldn’t install service without problem?
Xnet which you used in your script working excellent so fare (I tested it by installing su service on 4 workstations) the strongest thing in this command that it could install service on a workstation connected to the network but the user didn’t accessing our main domain.

But I still have a little problem with this command which is how can I copy the Suss.exe to these workstation where the user doesn’t access the main domain (if he does,I can place script to copy these file to him)?

In the INI file work with Rservice.exe (Nt Resource kit) you can place files needed for installing the service and the command will copy them from your source workstation to the target before installation but unfortunately this command doesn’t work with Local system account feature.

I am looking for any idea or help.

Thank you very much.
