InGroup function is not working on Windows 10. Same script is working fine on Windows 8, 7 and older. I updated Kix to 4.66 but didn't help. After further research, I noticed InGroup fails when used with AD groups with "Universal" scope property. But if I use an AD group with "Global" scope, it works fine. Like I said, this was not an issue on Win 8/7/2k/etc. I'm hoping to find a way to resolve this on the client side (image settings, policy, registry, etc.) without making changes to AD groups (Universal to Global scope). Thank you.
