· Task Manager does not open.
· Windows Explorer becomes unresponsive.
· The computer stops responding to new RDP connection attempts
· Existing RDP sessions hang or time out.
When this problem occurs you may have to wait for some time for the server to become responsive again. This problem can occur when CCMEXEC (SCCM Inventory Process) performs a NtQueryDirectoryFile call to scan or query the contents of folders containing more than 20,000 files.
For all the latest information and the current recommended workaround see the following Knowledge Base article:
