Our office have a network printer on a window 2000 server. Previously, we use ip connection, such as \\192.168.1.34 then pop-up a login window, and input the username and password, I can see the printer. Now, after I upgrade my vista to windows 7, when the pop-up login appears, I see a domain with my computer name, and if I use the previous username and password, I cannot login, saying 'Logon failure: unknown user name or bad password'. I guess it's because I use a wrong domain name, but in windows xp and windows vista, no such domain name is used. What's more, I install the windows xp mode in the windows 7, and using the same login method, I can connect the printer without any problem. So I guess the problem is how to connect a printer without a domain name? the printer should in a workgroup not a domain. BTW, I cannot find the printer from 'add a printer' either in windows xp or windows 7.

Hi, Can you access Windows 2000 shared folder from Windows 7 machine? Is the Windows 7 machine in a domain? If there is no domain, please put the Windows 7 machine to the same Workgroup with Windows 2000. After that, please type the UNC path (\\192.168.1.34) and when the window pops up, please type the Computer name and password to access the network printer. If the issue persists, please also try the following steps. 1. Temporarily turn off firewall on the Windows 7 machine. 2. Modify relevant settings on Windows 7 machine. a. Click Start and open Control Panel. b. Open "Network and Sharing Center" and click "Advanced sharing settings". c. Expand the current network profile (such as "Home or Work"), and then select the following options: "Turn on Network Discovery", "Turn on file and printer sharing", "Turn on sharing so anyone with network access can read and write files in the Public folders", "Turn off password protected sharing" 3. Please open gpedit.msc in Start menu on the Windows 7 machine, locate to the branch Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\. Then make the change on the policy Network security: LAN Manager authentication level. Change to “Send LM & NTLM - use NTLMv2 session security if negotiated”. 4. Write down the IP address for Windows 2000. Click Start button in Windows 7 and type \\Windows 200 IP address, and then press enter. Can you access the Windows 2000 computer now? If there is any error message or the user name and password still cannot pass, please capture the window and upload it for research. Thanks, Novak
