I have a 2nd computer that I’ve installed Microsoft SQL Server 2008 Express on. I got it up and running with SQL Server Management Studio and created some tables and stuff.
But I want to be able to connect to it from my other PC, the one I usually work on in my home. But when I try to make a connection I get this error:

Now, I’ve checked a couple of things:
- doing a
\\SERVERin explorer from my computer works. So im guessing DNS is ok. - I’ve tried to turn the firewall on the server off, connect and back on again with no luck.
- both SQL Server (
SQLEXPRESS) and SQL Server Browser services are running (SQL Server Agent is not). - TCP on port 1433 is turned on.
Server name: SERVER is a result in the dropdown there.
1) It sounds like the instance you’re trying to reach is SQL Express. In which case the instance will be called
myserver\sqlexpress(“SQLEXPRESS” literal; case doesn’t matter). “myserver” won’t work with a “named instance”; “myserver\sqlexpress” might do the trick.2) You MUST enable TCP/IP with the SQL Configuration tool (installed when you installed MSSQL and SSMS).
3) You should turn off the firewall (brute force – don’t do it if you don’t have to) or enable MSSQL in the firewall (MSSQL is not enabled by default)
‘Hope that helps – please post back what you find.
