This article was previously published under Q134385 SYMPTOMS
On your computer running Windows NT, you can view files on a Novell
NetWare server from File Manager, but you cannot open these files or copy
them to a local drive.
The Event Viewer shows the following error:
Event Id 8007: The Microsoft client service for Netware redirector has
timed out a request to <NetWare_server_name>.
These symptoms occur when you use Windows NT on an Ethernet network
segment with Client Services for NetWare (CSNW) or Gateway Services for
NetWare (GSNW) installed, and attach to a Novell NetWare server connected
to an FDDI ring. RESOLUTION
To work around this problem:
- Decrease the packet size from 4202 to 1514 on the NetWare server.
NOTE: This solution negatively impacts the performance of the NetWare
server on the FDDI ring.
- Set DefaultMaxPacketSize to 1012. To do this:
WARNING: Using Registry Editor incorrectly can cause serious, system-
wide problems that may require you to reinstall Windows NT to correct
them. Microsoft cannot guarantee that any problems resulting from the
use of Registry Editor can be solved. Use this tool at your own risk.- Run Registry Editor (REGEDT32.EXE).
- From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\SYSTEM\CURRENTCONTROLSET\SERVICES\NWRDR\PARAMETERS - Add the following value:
DefaultMaxPacketSize:REG_DWORD: 1012 (decimal)
