Errors connecting to SQL Server Express 2005
Are you getting errors connecting to SQL Server Express 2005 via remote client
software and yet
have no problem connecting to it on the local machine?
Some of the errors you might be seeing are:
- sql server does not allow remote connections
- SQL Network Interfaces, error: 26 - Error Locating Server/Instance
- An error has occurred while establishing a
connection to the server. When connecting to SQL Server 2005,this
failure may be caused by the fact that under the default settings SQL
Server does not allow remote connections.(provider:Named Pipes
Provider,error:40-Could not open connection to SQL Server))
- Server does not exist or access denied
If yes, then read on because SQL Server Express 2005 is not automatically
configured for remote access during installation. It can be enabled however,
so the problems you are having are more of a
"feature" than a bug.
Why this page?Well, we too ran into this problem - just as you have
now. In recognition of all of the kind help we received from the Internet
newsgroups we thought it might be useful to collect the information here so
as to provide assistance to others in the same position.
Here's a quick summary of the actions you need to take. The first
three actions have a separate page which provides more details and some
screen shots of the procedure.
Enable the TCP/IP protocol using the Surface Area Configuration Utility
- [Link] Make sure the TCP/IP protocol is
enabled in the SQL Server Configuration Utility
Make sure the SQL Server browser is started. Note this step
is optional. It is possible to set the SQL Server instance to use a fixed IP
address - but this is non-standard for named instances.
- Make sure SQL Server and SQL Server Browser are exempted by the firewall
on the server machine. This is done by putting sqlservr.exe and
sqlbrowser.exe as an exception in the
windows firewall. Chris D. sent in a
which might help.
- Note: In order to get things to work. You might need to completely
reboot the server machine after making the changes. There have been reports that
starting and stopping the
SQL Server and Browser software is not enough.
