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.
