SUMMARYWhen you use Microsoft Query, when you try to connect to an SQL Server database, you may receive an error message similar to the following:
CAUSE
If the client workstation is running Microsoft Windows for Workgroups
version 3.11 client (WFW 3.11) and the SQL Server is on a Microsoft Windows
NT version 3.5 server, you may have a feature called "direct hosting"
enabled. Direct hosting allows the virtual redirector on the client side
and the network server on the server side to communicate directly with the
underlying NWLink transport, bypassing NetBIOS, which provides faster
performance. However, direct hosting can prevent existing WFW 3.11 clients
from reliably connecting to the NT SQL Server.
RESOLUTIONSTo correct this connection problem, you can use either of the methods below.
Method 1: Update your Windows for Workgroups 3.11 files: There are six updated Windows for Workgroups 3.11 system files that include a new version of the Windows for Workgroups redirector and other network support files that provide improved performance. These files are distributed on the Windows NT Server version 3.5 CD, in the CLIENTS\WFW\UPDATE directory. These updated files are the following:
These files should be used only for WFW 3.11. They will allow named pipe connections to work properly to Microsoft SQL Server over direct host IPX. To install these new files on a computer running WFW 3.11:
Using any text editor, edit the SYSTEM.INI file to set DirectHost=off in the [network] section as shown below: [network] DirectHost=off You need to reboot your client workstation after this modification.
