MSSQL + Eclipse = Problem na porcie 1433

Witam, probuje sie polaczyc z MSSQL mniej wiecej tak:

    	try {
	    		Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
	    	      //con = DriverManager.getConnection("jdbc:sqlserver://localhost:5530/NB", "sa", "12345");
	    		con = DriverManager.getConnection("jdbc:sqlserver://localhost;user=sa;password=12345;databaseName=NB");  
	    		if(!con.isClosed());
	    	      
	    	    } catch(Exception e1) {
	    	      System.err.println("Exception: " + e1.getMessage());
	    	    } finally {
	    	      try {
	    	    	statement = con.prepareStatement("SELECT surname FROM tab1 order by name asc");
	    	    	rs = statement.executeQuery();
	    	    	while(rs.next()) rowcount++;
	    	    	
	    	    	for(int i=1; i<=rowcount; i++)
	    	    		{
	    	    		if (rs.absolute(i)) 
	    	    			zmienna = rs.getString("surname").trim();
	    	    		tekst.setText(zmienna);
	    	    		//ListaGlowna.add(zmienna);
	    	    		}
	    	    	if(con != null)
	    	        con.close();
	    	      } catch(Exception e1) {}
	    	    }

Program sie kompiluje ale jak chce polaczyc sie z baza krzyczy:
Exception: The TCP/IP connection to the host localhost/DCPC2011/DBPC, port 1433 has failed. Error: "null. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port.".

Wchodzilem juz w SQL Server Configuration Manager -> TCP/IP -> IP Adress ustawilem All IP dla TCP IP PORT 1433 i nic wciaz ten sam blad ... zetknal sie ktos z podobnym problemem ? jak go obejsc by polaczyc sie z baza ?
