Windows 2008R2 server had 2 instances of SQL 2005 installed, BACKUPEXEC and ACRONIS.
I installed SQL 2008R2 Express (64 bit), created database, and our software runs fine on the server.
When I try to run our software from a workstation, this error appears:
Connection failed:
SQLState: '08001'
SQL Server Error: -1
[Microsoft][SQL Native Client]SQL Interfaces: Server doesn't support requested protocol [xFFFFFFFF].
Connection Failed:
SQLState: 'HYT00'
SQL Server Error: 0
[Microsoft][SQL Native Client]Login timout expired
SQLState: '08001'
SQL Server Error: -1
[Microsoft][SQL Native Client]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 setting SQL Server does not allow remote connections.
I have tried establishing a connection using ODBCAD32, and I can select the correct instance
using this tool, but I still get exactly the same error message.
Since I am not responsible for the software running on SQL 2005, I am trying to be cautious in making any configuration changes.
The SQL 2005 install is 32 bit, while the SQL 2008R2 install is 64 bit (I can reinstall 32 bit version if this is an issue).
SQL Server Browser is running, but it is the 2005, 32 bit version that is running.
Windows firewall was turned off.
Any help would be appreciated.
