DOCUMENT:Q183203 10-AUG-2001 [winnt] TITLE :Print Queue Backs Up When Connected to NetWare Server via LPR PRODUCT :Microsoft Windows NT PROD/VER:WinNT:3.51,4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server versions 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Your Windows NT Print Server may back up or not complete print jobs when it is configured to send print jobs to a Novell NetWare Server through line printer remote (LPR). CAUSE ===== The Novell NetWare server may be resetting the Transmission Control Protocol (TCP) ports. RESOLUTION ========== To resolve this issue you will need to contact Novell technical support. For information about how to contact Novell, query in the Knowledge Base for one of the following articles: ARTICLE-ID: Q65416 TITLE : Hardware and Software Third-Party Vendor Contact List, A-K ARTICLE-ID: Q60781 TITLE : Hardware and Software Third-Party Vendor Contact List, L-P ARTICLE-ID: Q60782 TITLE : Hardware and Software Third-Party Vendor Contact List, Q-Z STATUS ====== Novell NetWare is manufactured by Novell, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this products' performance or reliability. MORE INFORMATION ================ In high volume print environments, more then ten print jobs may queue up in the print spooler at the same time. Per RFC 1179, each one of these jobs opens a TCP session with the receiving line printer daemon (LPD) server. Although multiple sessions are expected behavior, when the Novell NetWare server sees that more than ten sessions are trying to setup from the same source address it incorrectly thinks it is under a SYN attack. To defend itself from this, it resets all connections from the source IP address.
