Remote access to Windows Computers (LogMeIn)

If you have been using LogMeIn to remotely access a Windows or Mac computer via a LEPP Computer Group provided link, you will now get an error message. This is because the method we have been using is being discontinued by the provider. If you still need remote access to your Windows or Mac computer, please open a service request at service-lepp@cornell.edu and we will send you the new link to use.

Document viewing in OWA: Temporary restriction

• Notice from CIT on Thursday morning, July 26:

Microsoft has disclosed a vulnerability in Exchange that affects document viewing in OWA. CIT has turned this feature off until Microsoft releases a patch. This feature provided a link following an attachment in the email labeled [Open as Web Page] which allowed you to view the attachment without downloading it first. Until a patch is released by Microsoft, you will have to download these attachments to view them. This restriction is necessary to protect Cornell's information and infrastructure.

CLASSE Migration for Linux and Web

With a long-term CLASSE perspective, both LEPP and CHESS computer groups have been planning for and taking steps to increase the coordination and collaboration between LEPP and CHESS computing systems. A successful first step has been the deployment of a CLASSE Active Directory domain that is currently being used to provide centralized authentication and authorization for Windows 7 systems. Moving forward the goal is for the CLASSE Active Directory to grow into a CLASSE single sign-on system supporting Windows and Linux systems as well as web-based services such as the CLASSE wiki, EDMS, ELOG, etc. When this migration if complete, many of our existing usernames and passwords, including the legacy LNSNTCAD and existing LEPP interactive and network unix passwords, will be obviated by your CLASSE credentials.

The migration to CLASSE AD will be a gradual long-term project. Any authentication changes will be announced and vetted in advance. While the migration and authentication changes may be painful at times, the benefits of moving to a unified CLASSE infrastructure are essential for most effectively supporting our research and education goals.

General network and server maintenance will occur every Tuesday from 12:00 noon to 2:00 PM. The CLASSE-IT group will always announce any expected disruptions in our NewsLetter and via CLASSE-IT-NEWS-L, but with the size and complexity of our network there is always the potential for something to go wrong. We will do our best to contain all network maintenance and planned outages to Tuesdays from 12:00 noon to 2:00 PM.

Unless other arrangements have been made, CLASSE-managed Windows systems may be updated and rebooted on Tuesday morning at 2:00 AM, so please avoid critical or lengthy operations at that time. For more details, please see SystemExpectations.
