Hi, According to your description, I suggest to perform these tests to troubleshooting the issue: 1 Disable “Password Protected sharing” on Windows 7 computer: 1) Open Network and Sharing Center. 2) Click “Change Advanced sharing settings”. 3) Select “Turn off password protected sharing” under “Turn off password protected sharing”. 2 Change the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa LmCompatibilityLevel to 1, then restart If the issue persists, you can try the suggestion mentioned in: http://social.technet.microsoft.com/Forums/en/w7itpronetworking/thread/aaa611cb-a9bc-4fbf-8095-9d0fa6654ca5 “Check win7 and win2000 time and zone setting” Hope that helps.

Hi, thanks for your reply. I didn’t find the option “Turn off password protected sharing” in my advanced sharing settings, maybe because the pc is inside a domain? The key on the windows registry was already set as suggested. No lucky, it still doesn’t work… I also checked as suggested time and zone setting: in the windows 2000 server is set the zone GMT + 1.00, in the Windows 7 pc is set UTC + 1.00. I have no idea what try to do… is there any way to debug the connection? Can I see the operation step by step? I really don’t have any idea of what to do… Thanks for your help, best regards

Good morning, I have a big problem: I bought for my company 4 brand new pc with Windows 7 Professional installed. I added my pc’s to my domain but I can’t access to the share on the windows 2000 server. When I try to connect to the server appears a message that ask for my credential. I can’t access also if I insert my credential. I tried to google a little bit for a solution and everywhere I found that I have to change the Lan Manager authentication level but it still doesn’t work… does anyone have an idea? How can I fix the problem? I have access on windows 2003 share without any problem… Thank you for your help, best regards
