SYMPTOMS
When Client Services for NetWare (CSNW) opens Microsoft Office files, delays may occur. The problem typically occurs when you are opening files on NetWare-based servers.



CAUSE
This problem occurs because CSNW continually resolves printer names, server names, and object properties. This causes poor performance. The problem becomes more pronounced as more clients perform the queries.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
