I just install a Windows 7 Home. However I cannot login to the server 2000 which in my company.... My family of computer was set Domain. The error was just the incorrect login name or passwords, but I already confirmed the id and pin were correct. Why? How to solute that?

Home computers can not join a windows domain, only Windows 7 Professional, Enterprise and Ultimate can. http://windows.microsoft.com/en-US/windows7/products/features/domain-join However your choice of words leave some confusion when you mention ID and PIN. Also it appears English isn't your native language. My suggestion is to use the Langauge pull down above and choose a langauge more suitable to you for better clarification and understanding.You can consider HOMEGROUP and here's a tutorial on how to do that http://www.howtogeek.com/howto/windows-7/share-files-and-printers-between-windows-7-and-xp/ and more about homegroup FAQ http://windows.microsoft.com/en-us/windows7/HomeGroup-frequently-asked-questions One possible solutionThe server is stand alone in the same workgroup with the other PCs. Anyway that seems to be a problem of windows 7 home since ultimate and professional edition connect properly to win 2000 share using the same user and password which that I am using with win7 home ed. I guess that the windows 7 pc does not send the proper authentication info to the remote pc. The solution: Registry editing for LAN manager authentication level (in Home edition this can be configured through registry) How to do it: 1 . Open registry editor ( Start search - regedit)2 . Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa3. Create a new DWORD value with the following properties: NAME: LmCompatibilityLevel VALUE: 14. Restart your PC and try the connection again...Read on for more info:Problems sharing files between computers on a network are generally caused by 1) a misconfigured firewall or overlooked firewall (including a stateful firewall in a VPN); or 2) inadvertently running two firewalls such as the built-in Windows Firewall and a third-party firewall; and/or 3) not having identical user accounts and passwords on all Workgroup machines; 4) trying to create shares where the operating system does not permit it.In Windows 7, go to Control Panel>All Control Panel Items>Network and Sharing Center. Click on "Change advanced sharing settings". You don't want to use Homegroup unless you have all Windows 7 machines. If you do and you want to use Homegroup, see Windows 7's Help & Support. Otherwise, in the Advanced Sharing:Turn ON network discoveryTurn ON file and printer sharingTurn ON sharing in the Public folder sharing sectionTurn ON password protected sharingA. Configure firewalls on all machines to allow the Local Area Network (LAN) traffic as trusted. With Windows Firewall, turning on Windows 7's File and Printer Sharing as above will take care of this for you. If you aren't running a third-party firewall or have an antivirus/security program with its own firewall component, then you're fine. With third-party firewalls, I usually configure the LAN allowance with an IP range. Ex. would be 192.168.1.0-192.168.1.254. Obviously you would substitute your correct subnet. Refer to any third party security program's Help or user forums for how to properly configure its firewall. Do not run more than one firewall. DO NOT TURN OFF FIREWALLS; CONFIGURE THEM CORRECTLY. B. For ease of organization, put all computers in the same Workgroup. This is done from the System applet in Control Panel, Computer Name tab.C. Create matching user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and the passwords assigned to each user account can be different; the accounts/passwords just need to exist and match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY SIMPLE ONES . If you wish a machine to boot directly to the Desktop (into one particular user's account) for convenience, you can do this:Start>Search box>type: netplwiz [enter]Click on Continue (or supply an administrator's password) when prompted by UACUncheck the option "Users must enter a user name and password to use this computer". Select a user account to automatically log on by clicking on the desired account to highlight it and then hit OK. Enter the correct password for that user account (if there is one) when prompted. Leave it blank if there is no password (null).D. If one or more of the computers on your network is XP Pro or Media Center, turn off Simple File Sharing (Folder Options>View tab).E. Create shares as desired. In Windows 7 I usually share out the user's Desktop and the Public directory.F. After you have file sharing working (and have tested this by exchanging a file between all machines), if you want to share a printer connected locally to one of your computers, share it out from that machine. Then go to the printer mftr.'s website and download the latest drivers for the correct operating system(s). Install them on the target machine(s). The printer should be seen during the installation routine. If it is not, install the drivers and then use the Add Printer Wizard. In some instances, certain printers need to be installed as Local printers but that is outside of this response.MCSE, MCSA, MCDST [If this post helps to resolve your issue, please click the "Mark as Answer" or "Helpful" button at the top of this message.

Do you mean you are trying to login to the server that is in your company from your Windows 7 Home Premium computer at home? If so, you'd better to contact the network administrator at your company and ask if your company domain allow this kind of accesses. If you just try to connect to the server when you are in the company, I suggest you change the NTLM authentication level in Windows 7 as cdobbs suggested.Arthur Xie - MSFT
