Impossible I keep kix32.exe in \\bstl_svr1\netlogon (Only one DC)

When I browser the network,I can see all the file in this file sharing (\\bstl_svr1\netlogon).

If I'm specify path I can't run it.

In our network, my client has many client such as 98,NT,2000 and XP.

How I can specify the script in User Profile.
