Some Share Names May Not Work Correctly

ID: Q225255


The information in this article applies to:
  • Microsoft Windows NT Server, Enterprise Edition version 4.0, used with:
    • Microsoft Cluster Server
  • Microsoft Windows NT Server version 4.0
  • Microsoft Windows NT Workstation version 4.0


SYMPTOMS

If you use one of the following names as a share name, some API operations on this share will fail:

M, MA, MAI, MAIL, MAILS, MAILSL, MAILSLO, MAILSLOT
While MAILSLOT is a reserved name, the other share names are legal regardless of case.

A known API call is FindFirstFile(). It may fail with an error 1 "Incorrect function". Unfortunately, Microsoft Cluster Server uses this API call to verify if the share name is alive.


CAUSE

The share name was compared against the string "MAILSLOT" and found identical, even if the share name was shorther than eight characters.


RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
