It looks like it's going to work well (still testing with a small group), and best of all, the "Multiple Computers" function works great!
I've got it so that netlogon.bat executes on startup by adding \\<fileserver netbios name>\netlogon\netlogon.bat, but I am prevented from rerunnin gnetlogon.bat after logon, even though I've specified H:\netlogon.bat. I've attached a screengrab - does anyone see anything illogical in it? The first line in the allow list was an attempt to have Trustnoexe to recognize the logged-in user, but doesn't work.
This is merely a small inconvenience - thank you David for pointing me to this app!!
