Recent Patch breaking GPOs?

[Steve21]

Afternoon All,

 

Anyone know if there's been a recentish patch that's borked most GPOs applying (Specifically Drive maps too)? We're getting an odd issue where a bunch of machines suddenly decide they'll take near enough an hour to logon to and all stick on applying GPOs. Yet the machine next to them works fine and logs in the normal time.

 

Looking at the logs it seems all GPOs taking huge amount of time to apply, and it's adding up to nearly an hour (56 minutes in the below example):

 

The winlogon notification subscriber took 3401 second(s) to handle the notification event (Logon).

 

Thanks,

Steve
