Domain Controller Firewall Rules (SMB1)
Between 9 and 9:30 a.m. on Thursday, April 24, campus domain controllers will be updated to deny access to systems that rely on the SMB1 protocol, which is obsolete and less secure than the current SMB versions used on campus.
Impact
During the maintenance window, users may experience delayed authentication of domain controller queries.
After maintenance is complete, if you notice that an application has started timing out when connecting to the campus network, please contact the IT Service Center at 303-735-4357.
