Re: Cannot connect to SQL express database ????

Connecting to the server name (<myPCname>\SQLEXPRESS) should work, if the SQL Server Browser service is running. However, yes, you are correct that if SQL Server Express Edition is using dynamic ports, then the port could change to one that is blocked by the firewall. So you will need to switch SQL Server Express Edition to a fixed port.

OK it works now rick...
I have made 2 mistakes...
Frist of all I forgot to open the port 1500 in my windows firewall.
Then I was accessing my server by using <myPCname>\SQLEXPRESS as I use to do
normally with SQL server.

SO in order to work I have to connect using tcp:<myPCname>\SQLEXPRESS,1500

But I like whem I undersatnd things. This connection string using sytax
above is use like that only for this express edition ? I guess not, I mean I
have made many connection like that with SQL server ( On a real server sure)
and I was juist using the instance and Pc name.

Or may be it would work also if I add left the default setting when you use
TCP as port 1443 and let SQL as dynamic mode and then just open the port 1443
on my firewall. Then use as connection string :<myPCname>\SQLEXPRESS.

But of course dynamic means dynamic.
Does it means that this dynamic TP port seting should never be use with SQL
server ?

Are you attempting to connect to the Express Edition by name in the format
computer_name\SQLExpress ?
Is the SQL Server Browser service running?
Can you connect to the Express Edition by the port number using
computer_name,1500 or by IP address in the format 127.025.144.315,1500 ?
