hi everybodyI've been working in the database field for 9 monthsI started from very simple tables, to some sql stuffAnd then I started studying SQL Server 2005 extensively until I took MCTS SQL Server 2005During that time, I was building a database for a new company from scratch, and while I build it for them I keep on reading books and learning, and using this knowledge to upgrade the databaseRecently, I could successfully migrate the back-end to SQL Server 2005, and after days of struggling I could connect the front end to it via ODBC in a LANMy next step is connecting the database through the internet, so I just changed the server name in the DSN file to the address of the server, and opened the ports, but it didn't work....Can you tell me what's the problem?Is there a book that can help me do this thing?I can buy any book and I have the will to learn, provided that I'll apply for MCITP Database Developer next monthsThank you.. |

What do you mean dynamic ip? Got ip address via dhcp? Is the ip address a valid internet address? |

Is it your company's internal ip address? Will not work if so. |

the problem is not with the port or the ipi already checked that the port is open, and that the dynamic dns is working, and i'm sure about it |

Nothing to do with your dns, have to register your server in internet domain's dns. |

Every machine on network has ip address, don't know what you mean 'have a dynamic dns account with no-ip'. |

i mean, i have a free domain address from no-ip.biz that points to my ip whenever it's changed, and that's why it's dynamic...i use this domain address (something.no-ip.biz) to connect to my home computer because it has a dynamic ip |

You said you can connect from lan but not via internet in first post, then you said ping from internet works above. Now you have another store, looks like you need find some local help. |
