SCCM KB4018655 clients reinstall every five hours.
概括
A Microsoft System Center 2012 or System Center 2012 R2 client installation (CCMSetup) initially fails and causes a client retry task to be registered in 视窗 Task Scheduler. After the client installation succeeds, the retry task is not deleted as expected. 所以, the clients continue to reinstall every five hours.
在这种情况下, if you upgrade the System Center 2012 配置管理器 infrastructure to 系统中心配置管理器 当前分行 or Long-Term Servicing Branch, and if you do not upgrade the System Center 2012 配置管理器 clients, the scheduled retry task continues to force a client reinstallation every five hours.
The next time that CCMSetup runs, the clients find an updated management point or 分发点, and they reinstall the client software. This upgrades the clients to 系统中心配置管理器.
These continual upgrades occur outside the normal upgrade process that is configured by the administrator. This includes the client piloting feature.
Symptoms
In a Microsoft System Center 2012 or System Center 2012 R2 environment, you notice the following symptoms:
- Clients successfully reinstall themselves every five hours. This activity is logged in the ccmsetup.log and 视窗 event logs.
- When you view the \Microsoft\Microsoft\ConfigurationManager folder in Task Scheduler, you find a task that is named “Configuration Manager Client Retry Task.”
Cause
This issue occurs because CCMSetup creates the client retry task in the wrong folder on the client. This prevents CCMSetup from locating and removing the task.
The scheduled task is created in the “\Microsoft\Microsoft\Configuration Manager” folder instead of the “\Microsoft\Configuration Manager” folder.
Workaround
To work around this problem, remove the retry task. 要做到这一点, use one of the following methods.
方法 1
Manually remove “Configuration Manager Client Retry Task” from the “\Microsoft\Microsoft\Configuration Manager” folder by using Task Scheduler.
方法 2
Deploy a script to remove “Configuration Manager Client Retry Task” from the “\Microsoft\Microsoft\Configuration Manager” folder.
