Removing Bypass Traverse Checking Causes Copy to Drop Streams

• Microsoft Windows NT Server versions 4.0

SYMPTOMS

Files contained in Macintosh volumes contain streams (special data content) that include data fork information. Files that do not contain stream information appear to Macintosh clients as text-only files. The reported problem occurs after copying a file from one directory to another. The copy operation could be performed from the computer running Windows NT Server or by a Macintosh client; it made no difference. After the copy operation, the target file stream was lost and the file appeared to Macintosh clients as a text-only file.

This copy problem occurs on PDC or BDC servers, but not on a member server. It also occurs when the Domain User Rights for "Bypass Traverse Checking" (the default is Everyone) has been modified so no users are granted this right for the Domain.

CAUSE

NTFS was making a check that precluded the copying of the streams in the case where "Bypass Traverse Checking" was removed from user rights.

RESOLUTION

The issue has been resolved in the latest version of the Ntfs.sys driver. Obtain the following fix or wait for the next Windows NT service pack.
