Why has the NT File Replication System (NTFRS) stopped responding?

A. A typical cause for this problem is that the NTFRS's intermediate storage area, the staging area, is full. The staging area stores data as it travels between the network drive and the final local destination. Because data can move faster locally than across the network, this area's space fills quickly when you replicate large amounts of data. By default, the system allocates 660MB for the staging area, but you can increase this value if the staging area volume has sufficient free space.

Before you make the change, you must determine the hexadecimal value of the required size in kilobytes. For example, if you need a 1GB staging area (1,000,000KB), you would perform the following steps to calculate the hex value:

  1. Start calc.exe.
  2. From the View menu select Scientific.
  3. Set the type to Dec.
  4. Enter the number in kilobytes (in this example, 1000000).
  5. Set the type to Hex. The number will change to the hex equivalent (in this example, F4240).
  6. Note the hex value.

To increase the staging area's size, perform the following steps:

  1. Start regedit.exe.
  2. Navigate to
  3. Double-click the "Staging Space Limit in KB" value.
  4. Change the base to Hex, and enter the value (in this example, F4240).
  5. Click OK.
  6. Close regedit.
