Q237181: Some LPD Print Servers Reject an LPD Connection from Windows NT

Article: Q237181
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbWinNT4sp6fix

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0, Terminal Server Edition 
- Microsoft Windows NT Server version 4.0

-------------------------------------------------------------------------------

SYMPTOMS
========

When print data is sent from a NetWare client to a computer running Windows NT
Server and Microsoft File and Print Services for NetWare (FPNW), Windows NT's
LPR sends a packet, whose format violates RFC1179, to the LPD print server (for
example, UNIX). Some LPD print servers reject the attempted connection because
of the invalid packet. As a result, NetWare clients cannot send print jobs to
LPD print servers using a computer running Windows NT server and FPNW.

CAUSE
=====

This problem occurs because RFC1179 states that host name field in a packet
using the LPD protocol must contain 31 or fewer characters. When a print job
comes from FPNW, Windows NT's LPR sends a packet that contains more than 31
characters in the host field to the LPD print server. This causes the packet and
LPD connection to be rejected by some LPD print servers.

RESOLUTION
==========

Windows NT Server or Workstation 4.0
