Bugs[edit | edit source]

Using ntdsutil.exe to move Active Directory files may fail with the error message "“Move file failed with source <original_full_db_path> and Destination <new_full_db_path> with error 5 (Access is denied.)”.
Auto-logons that are configured by login scripts do not work properly.
The status of the online/offline files icon and status bar may not display an accurate status. The OfflineFiles event manager logs will show the actual state of the files.
PowerShell may report an incorrect NdisPhysicalMedium result on an IPoIB adapter.
(This bug only impacts the mmc.exe found in the Application Compability Feature on Demand package set) Multiple instances of the Active Directory Users and Computers snap-in added to the same mmc.exe instance could show inconsistent or no data on part of the snap-ins after adding extra columns to the UI view. The workaround is to use a separate MMC session for each ADUC (dsa.msc) snap-in.
Scheduled startup tasks may not run. If this occurs, the system logs an event, which is ID 101 with the error code ERROR_LOGON_FAILURE.
DCPromo will fail if the interface metric of the physical NIC is larger than the loopback interface.
If a domain controller is renamed, the system does so, but it updates incorrect attributes in AD, leaving orphaned data behind (ValidateSPNsAndDNSHostNameActual). This bug can be reproduced by adding a new FQDN, setting that as primary, restarting the domain controller, then removing the current FQDN. Checking the msDS-AdditionalDnsHostName, msDS-AdditionalSamAccountName and the servicePrincipalName attributes will show incorrect values.
Self-service users can't install Feature on Demand and Language Pack packages for Windows Server Update Service (WSUS), System Center Configuration Manager (SCCM), and Autopilot scenarios.
After disabling and re-enabling SR-IOV capability on a Linux VM, Windows may report the error "Error applying Network Adapter changes.” Analyzing the details will show “The Hyper-V Virtual Machine Management service encountered an unexpected error: Call was canceled by the message filter. (0x80010002).” Because of this error, the VM will remain in a stopping state when shutting it down, thus making it impossible to shut the VM down until the computer is restarted.
When deploying a controller VM, after the last reboot in the deployment process, the controller VM is not visible.
