This article was previously published under Q108827

SUMMARY

The number of connections to SQL servers is limited under Microsoft Query. Attempting to make more than 14 connections to SQL servers will result in the following error message:
ConnectionOpen (sopen()).
Unable to connect to data source
Connecting to 14 SQL servers and then making a connection to a dBASE source and adding a table will result in the following error message:
Can't access table <path\filename>
Choosing OK to this error message and again attempting to connect to a dBASE data source will result in another error message:
Data source not found and no default driver specified

MORE INFORMATION

The above error messages result from a limited number of Microsoft Query connection handles. There are no settings in either the application or the ODBC drivers to correct this. Connections to SQL server take one connection handle each. Attempting to make a fifteenth (15th) connection will result in an error.
