I'm having a strange problem with this but I know (and admit) that the problem is on my PC and nowhere else. My firewall was causing a problem because I was unable to PING the database server, switching this off gets a successful PING immediately. The most useful utility to date is running netstat -an in the command window. This illustrates all the connections that are live and ports that are being listed to. I can establish a connection both by running

telnet sql5.hostinguk.net 1433 and

sqlcmd -S sql5.hostinguk.net -U username -P password

See below:

Both these utilities show as establishing a connection in netstat so I am able to connect the database server every time, this worked throughout yesterday and has continued this morning.

The problem is when I attempt to use SQL Server Management Studio. When I attempt to connect to tcp:sql5.hostinguk.net, 1433 nothing shows in netstat at all. There is an option to encrypt the connection in the connection properties tab in management studio, when I enable this I do get an entry in netstat -an, see below:

TCP 81.105.102.47:1138 217.194.210.169:1433 TIME_WAIT

TCP 81.105.102.47:1139 217.194.210.169:1433 TIME_WAIT

TCP 81.105.102.47:1140 217.194.210.169:1433 TIME_WAIT

Amost as if it's trying the different ports but you get this time_wait thing. The error message is more meaningful and hopefull because I get:

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (.Net SqlClient Data Provider)

I would expect this as the DNS has not been advised to encrypt the conection.

This is much better than the : Login failed for user 'COX10289'. (.Net SqlClient Data Provider) that I get, irrespective of whether I enter a password or not.

This is on a XP machine trying to connect to the remote webhosting company via the internet.
I can ping the server
I have enabled shared memory and tcp/ip in protocols, named pipes and via are disabled
I do not have any aliases set up
No I do not force encryption
I wonder if you have any further suggestions to this problem?

I'll create an alias with ip address and port number, then connect to sql server with alias in ssms.
