<SQL Server>Db-Library network communications layer not loaded
Posted on 2009-05-19
We want to use Lotus 123 for DOS, a legacy spreadsheet software, to connect to SQL Server 2005 database. It should be possible, based on the documentation. When I try to connect, I get a Backend DataBase Error. I press F1 and it gives me a message: <SQL Server>Db-Library network communications layer not loaded.
I am not sure what is causing the error.
Lotus provides a DataLens driver which uses the Db-Library supported by older versions of SQL Server instead of ODBC or OLE DB. SQL Server 2005 still supports connections using Db-Library according to their website. I have the Db-Library file (ntwdblib.dll) int the C:\Windows\System32 folder on both computers.
Here is a copy of the text in the C:\Lotus40\Lotus.BCF configuration file:
DN="SQL_Clients" DL="DLSM" DD="DataLens driver for SQL database" AC=UI,PW
DC="$CF SQLSDL $SV LVASQLS $OP PHARES3400";
All the files mentioned in the configuration file are in the C:\Lotus40 folder. PHARES3400 is the name of the computer on which SQL Server is installed; this computer is running WinXP Pro SP2. The Lotus computer is also running WinXP Pro SP2. I don't think we have any connection issues because I can open a connection easily in Excel on the Lotus computer. I have TCP/IP enabled on the database. I have been able to connect to an old FoxPro database, so I know Lotus can do databases.
btw. It is not feasible to upgrade our spreadsheet software. Won't happen!
I am curious to know if there are any experts that still remember how to make Lotus do it's tricks. I need to know what is causing the error and how to fix it.
Thanks in advance
