DOCUMENT:Q216905 16-MAY-2002 [winnt] TITLE :Downlevel Clients Can Cause Excessive Spooler CPU Usage PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 OPER/SYS: KEYWORDS:kbWinNT400sp5fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== Connecting to a Windows NT print queue from a Microsoft Windows 95 or Windows 98 client can cause the spooler process (Spoolss.exe) to approach 100 percent CPU usage if a large number of print jobs are in the queue. Another possible symptom of this issue is that the print queue window on the client may become unresponsive. A network trace between the client and the print server shows continuous remote procedure call (RPC) traffic as the client repeatedly attempts to enumerate the list of print jobs in the queue. Windows NT clients are unaffected by this issue. CAUSE ===== This problem occurs because the number of print jobs that the downlevel client can retrieve exceeded the 64 KB limit. 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: - http://www.microsoft.com/Windows/ServicePacks/ -or- - Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack For information on obtaining the individual software update, contact Microsoft Product Support Services.
