SYMPTOMS
While an Infrared (IR) file transfer is occurring in Windows 2000, the receiving computer may enter Standby if the CPU utilization is low enough.

Example
One or both of the following conditions exist:
 * The receiving computer has a very fast CPU such as a 1 GHz or faster CPU.
 * The IR connection between the two computers is operating at a low transfer rate such as 57,600 bps or slower.

Under these conditions, the CPU activity that is required to continue receive the data may be very low. Because of this, the receiving computer may enter Standby while the transfer is still occurring. The CPU activity that is required to continue to receive data may be as low as 12 percent or less, and you can view this amount with Task Manager or System Monitor.



CAUSE
On Windows 2000, the Infrared transfer utility (Irmon.dll) does not signal the system to indicate that it is &quot;active&quot; while it is receiving a file by using an IR connection. If no user input occurs and the CPU utilization remains below a threshold of approximately 12 percent, the system appears to be in an &quot;idle&quot; state. The computer then enters Standby after the specified period of time passes.
