Windows-Delayed Write Failed

When my Marketing agent is trying to save an ad in Corel Draw9 she gets a “Windows – Delayed Write Failed” message. In the contents of this message it states that “Windows was unable to save all the data for the file\device\hardisk volume1\etc”. I have repaired Windows 2000 and Corel installations and still get this message. All devices have been unistalled and reinstalled and seem to be working fine. She has good network connections. I’m at a loss.
