Slow performance after you change the system time or resume the computer from sleep or hibernation on a System Center Configuration Manager 2007 SP2 client.

Q. SCCM Client is responding very Slow ?

Cause : This issue occurs because the System Center Configuration Manager 2007 SP2 client unnecessarily sends many WMI queries for the WM_TIMECHANGE message.

Solution :

1. You deploy many updates to a Microsoft System Center Configuration Manager 2007 Service Pack 2 (SP2) client.

2. You perform an operation that generates the WM_TIMECHANGE message from the client computer. For example, you perform one of the following operations:

- You change the system time.
- You resume a computer from sleep.
- You resume a computer from hibernation.

In this scenario, the computer runs slowly for some time. Additionally, the CPU usage is high, and the computer processes a heavy workload of disk I/O.
