(1 row(s) affected)

And a screen

Shortly,you installed MS SQL 2005 WRONG.

I edited the post.
Check it again.

Exactly how i supose,you don`t have the remote connections enabled,thats why you cannot connect.

But i thought i enabled them
But how to enable them ??

From Surface Area Configuration then choose Surface Area Configuration for Services and Connections after that go to Remote Connections check Local and remote connections then check Using both TCP/IP and named pipes after that click apply and it will require restart service,go to Service Stop service and Start Again then Apply ,OK ,NOW YOU REMOTE CONNECTION IS ENABLED ,now setup again your server using the user sa and password for it.

SQL SERVER CONFIGURATION MANAGER>>sql server 2005 network configuration>>enable TCP/IP and named pipes

I enabled them but still no succes.

firewall off?
try command: telnet winip 1433
post screen

Yeah all firewalls are off.

Are you sure you setup again the server with the right user sa and password for it and ip too for ms sql?

Yeah im 99,99% sure.
my mssql ip is my win ip thats 192.168.1.10
user sa
pass password
centOS ip 192.168.1.15
Setted in internal.txt
Forwarded all ports
patched login with lost-sprits patch.
Which client do i need to use?
i have a NON updated OGplanet

Doesn`t matter what you client you use,it matter only your enc and try make again my test with LoginSvr_01 if u remember!

How to set, that .enc files ?

I'll do the test again.

EDIT:
When i do emi's test again, the results are the same as my screenshot before.

EDIT:
When i do your test "amaymon" Service loginsvr_01 stop then the error is going away but still can't login.
