SYMPTOMS
Periodically all clients see delayed "buffered" keyboard input and programs temporarily are not responsive.



CAUSE
This issue can occur when a user logs on to the server with client printer mapping enabled.

Client printer mapping causes a large number of writes to the registry when a user logs in. These then have to be flushed to disk, and the registry flusher holds the registry lock exclusively while flushing. So, any program that tries to access the registry must wait until the flusher releases the lock, which can take several seconds.
