Group Policy Extension Failure
Group Policy uses the information collected during preprocessing to apply settings to the computer or user. The Group Policy service cycles through each client-side extension, sharing the previous collected information. Each client-side extension then applies its specific policy settings to the computer or users. During this process, one or more client-side extensions may report problems when attempting to apply policy settings.
