SYMPTOMS
When you connect to a Novell NetWare server from a computer that is running Client Services for NetWare (CSNW) and either Microsoft Windows 2000 Professional or Microsoft Windows XP Professional, you may experience one or more of the following symptoms:
 * Programs may not run as expected.
 * Saved data may be corrupted.
 * Your connection may stop unexpectedly.

When you use the Whoami tool on the Windows-based computer, the reported connection number may be different from the expected connection number.



CAUSE
This problem may occur if you have more than 255 connections to the NetWare server at the same time. When a connection is made to a NetWare server by a Client Services for NetWare client after 255 connections are made to the NetWare server, the connection numbers are counted again starting at 0. Two clients may have the same connection number.

For example, when the 270th user logs on to the NetWare server, the user is identified as connection number 14. Connection number 14 is also used by the 14th user to log on to NetWare. When the 270th user logs off from the NetWare server, the 14th user may also be disconnected from the NetWare server. Any data that is entered by the 270th user is actually owned by the 14th user.
