Warning!!!–Group Policy Logon Scripts Delays in Windows 8.1
”Last month, I wrote an article on the Petri.co.il website, reviewing the new features around Group Policy in Windows 8.1. Buried in that list of new stuff was a feature that was perhaps a little unheralded and under-advertised, but one that may cause administrators a world of hurt if they are not expecting it. Specifically, I’m referring to the change in Group Policy-based logon script behavior for Windows 8.1 clients. If you are using Group Policy-based logon scripts today to map drives or printers, set up registry or environment variables, etc., when you migrate your client machines to Windows 8.1, those logon scripts won’t run until FIVE MINUTES after logon has started. For some users, this could mean broken environments as processes or environmental setup steps that are expected to kick off at logon don’t.”
