Group policy cleanup and consolidation (9/5/2018 11:33:00 PM)
Starting now, and running through at least December, we will be deleting unused Group Policies, and merging and cleaning up existing group policies. This work is in preparation for upcoming Active Directory changes, and will be necessary to streamline the migrations that will be involved.
No significant changes are expected, but due to the nature of group policy editing, there is a small risk of error while editing and combining group policies.
Group policies which are not linked to any AD container will be deleted. There are a significant number of these discarded, and sometimes un-configured group policies, which we will delete to reduce the amount of work involved in the migration process.
Enable Windows 10 update distribution (3/15/2019 4:00:00 PM)
Windows 10 has an ability to help peer-to-peer share update files within the domain. This will be enabled for machines with a disk that is at least 360GB in size, and at least 20GB of free space. This will help distribute campus updates faster, and reduce the significant load we have seen on the campus update server, that has resulted in bottlenecks with update deployment. Tentatively this will be enabled campus-wide on March 15th, ahead of the March updates that will go out March 22nd. No significant end-user impact is expected, and testing is currently ongoing in the IS Security group of machines. This will also work on Windows Server 2019 servers, but will not help servers older than 2019 as this was only added by Microsoft to the newest server OS.
Yearly reset of KRBTGT password (3/17/2019 10:00:00 PM)
The campus krbtgt account will be reset to ensure a safe current password. This is done yearly to ensure that attackers cannot access this critical account. This may invalidate some active logons, but anyone active can re-authenticate to continue working. This is done after hours to avoid any issues. This has been done in prior years without any reported issues.
Firefox 60.5.2 ESR Campus Update (3/20/2019 10:00:00 PM)
Firefox 60.5.2 ESR will be replacing previous versions of Firefox on all faculty, staff, and lab computers to update campus to the newest ESR branch as well as addressing security vulnerabilities. The current deployed version is 60.3.0.

The following applications will be unable to obtain licenses during this time:
Wireless Core Router Reboot and Downtime (3/29/2019 11:45:00 PM)
Core3 will be upgraded with new supervisors and 10G linecards, requiring a code version increase and a few physical port moves. The only way to accomplish this is to shutdown the chassis while these physical changes are made, and then booting everything back up after all the new cards are in place. This upgrade stages our overall core routing environment in way to more easily integrate the new core3 replacement in the summer, as well allows us to enable features (like dual-stack IPv6) that we prior haven't been able to utilize. We are mindful that this hardware replacement will be impactful, so most of the work that can be done done will be done in an offline environment using an airgapped chassis of the same model.
