Netlogon Stops Reponding or Records Event ID 5703

 Last reviewed: March 24, 1997
Article ID: Q155523
The information in this article applies to:
  • Microsoft Windows NT Workstation versions 3.5 and 3.51
  • Microsoft Windows NT Server versions 3.5 and 3.51 --------------------------------------------------------------------------

SYMPTOMS

Users cannot log on to the domain, and the event viewer generates the following error: 

   Event id: 5703  Source: Netlogon
   The data area passed to a system call is too small.  Nt error 122.

CAUSE

This problem occurs if the Netlogon service receives a mailslot that is greater than the MAILSLOT_MESSAGE_SIZE (0x40c). This causes Netlogon to go into an infinite loop, filling the event log. At this point, Netlogon cannot respond to logon requests.

STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.5 and 3.51. A supported fix is now available, but has not been fully regression- tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Technical Support for more information.
