SYMPTOMS

In certain situations, your computer may stop responding, or hang, when it writes files or folders that are encrypted with the Encrypting File System (EFS) to a partition that is formatted with the NTFS file system. When your computer hangs, you cannot access the contents of the partition, and you have to restart your computer to restore functionality.

This problem has been reported to occur when your computer restores data to encrypted files by using VERITAS Backup Exec version 8.6 or later or by using NTBackup.exe. This problem may also occur when your computer writes EFS data with other programs.
