Review Known Issues, Limitations, and Recommendations for Running Task Sequences on Target Computers
The following is a list of known issues, limitations, and recommendations for running task sequences on target computers in MDT:
· For LTI deployments, ensure that User Account Control (UAC) is disabled for the built-in local Administrator account on the target computers until the task sequence finishes. Running task sequences on computers with UAC enabled for the local Administrator account causes task sequences to fail.
Note UAC should be disabled only for the built-in local Administrator account and enabled for all other accounts. By default, the built-in local Administrator account is excluded from UAC because of the User Account Control: Admin Approval Mode for the built-in Administrator account (disabled) policy setting.
For more information about UAC Group Policy settings, see UAC Group Policy Settings and Registry Key Settings.
