ACC: Disk or Network Error with Windows 95 Client on NT Server
ID: Q165351
|
The information in this article applies to:
-
Microsoft Access versions 2.0, 7.0, 97
IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, you should first make a backup copy of the
registry files (System.dat and User.dat). Both are hidden files in the
Windows folder.
SYMPTOMS
Advanced: Requires expert coding, interoperability, and multiuser skills.
When you run Microsoft Access on a Microsoft Windows 95 client computer,
and you link a Microsoft Access database on a Microsoft Windows
NT network server, you receive random occurrences of "Disk or Network
Error."
CAUSE
This error can occur as a result of many different situations, such as
faulty network cabling, noise or traffic in network lines, and problems
with network interface cards. However, in many situations Microsoft has
confirmed that using the IPX/SPX protocol as the primary network protocol
to communicate with a Windows NT 3.51 server may cause the problem. This
situation occurs when a Windows 95 client computer, using direct hosting
with IPX/SPX protocol, writes to a file on a Windows NT Server.
RESOLUTION
In addition to troubleshooting your network connections and network
hardware, you may be able to resolve the problem by disabling direct
hosting, upgrading to Microsoft Windows NT version 3.51 Service Pack 5, or
by implementing TCP/IP as the primary protocol.
Disabling Direct Hosting
The first method involves disabling the direct hosting feature for the
IPX/SPX protocol on both the client and server computers. The following
steps outline how to do this.
Disable Direct Hosting on the Windows 95 Client Computer:
WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall Windows 95. Microsoft cannot guarantee that
problems resulting from the incorrect use of Registry Editor can be solved.
Use Registry Editor at your own risk.
NOTE: For information about how to edit the registry, view the Changing
Keys And Values online Help topic in Registry Editor (Regedit.exe). Note
that you should make a backup copy of the registry files (System.dat and
User.dat) before you edit the registry.
To disable direct hosting in Windows 95, add a new string value named
DirectHost to the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Vxd\VNETSUP
Set the value for the DirectHost string value to 0.
Disable Direct Hosting on the Windows NT 3.51 server:
- Open Control Panel and double-click the Network icon.
- Click Bindings.
- Select Server->Nwlink Ipx/Spx Compatible, and click Disable.
- Click OK.
Upgrading to NT 3.51 Service Pack 5
The upgrade to Microsoft Windows NT version 3.51 Service Pack 5 contains a
fix that may resolve the networking problem with a Windows 95 client
computer.
For information about obtaining Service Pack 5, please see the following
article in the Microsoft Knowledge Base:
Q128465 How to Obtain Windows NT Version 3.51 U.S. Service Pack 5
Implementing TCP/IP Protocol
Another possible solution is to disable IPX/SPX on both the client and
server computers and implement TCP/IP as the primary protocol.
