(290) error on Progress clients using Windows Terminal Server and/or Citrix Metaframe

Intermittent Progress client disconnection using Terminal Server and or MetaFrame
SYSTEM ERROR: I/O error n in program, ret n, file n, addr n. (290)
SYSTEM ERROR: I/O error 22 in readit, ret -1, file 7, addr 0. (290)
Application files or executables located on file server on Terminal Server or Citrix machine.
No hardware issue on the server system

This was caused by a known Microsoft Bug:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q272582

This problem can be caused when the user that first opened the shared file logs off. The Terminal Server incorrectly closes the file handles that it has open to the remote file, so any other programs that had the file open are no longer able to access the file. Note that this problem does not occur if the data files are moved to a local volume on the Terminal Server.

Fixed in Service Pack 3 of Windows 2000

Hardware issues (network interface, RAM) have been reported to cause similar symptoms. The hardware should be troubleshooted as well if the issue occurs although the Microsoft issue has been solved.
It has not been confirmed that the Microsoft Service Pack 3 fixes all instances of this problem.
