We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SUMMARY
An Internet Information Server (IIS) with the Internet Database Connector, functioning as a client to Microsoft SQL Server may generate multiple error messages as databases are added to the Microsoft SQL Server.



MORE INFORMATION
The following errors have been seen when you use the IIS Internet Database Connector to make SQL requests to a Microsoft SQL Server that has a growing number of databases.

[State=01000][Error=231][Microsoft][ODBC SQL Server Driver]Pipe Busy.

[State=08001][Error=3][Microsoft][ODBC SQL Server Driver]Connection is busy.

[State=S1T00][Error=0][Microsoft][ODBC SQL Server Driver]Timeout expired.

This may be due to the SQL configuration parameter Open Databases being set too low, (20 is the default setting for SQL Server version 6.0). If you slowly add databases to the SQL system, and finally exceed the configured value, you may not generate any "out of open databases" messages being logged to SQL. Increasing the SQL configuration parameter Open Databases may resolve this issue.

For more information on setting this parameter consult the Microsoft "SQL Administrators Companion."
