Hi all, I didn't find the problem described below in another thread. I've got one XP-laptop, one Vista-laptop, one XP-desktop. All connected to a speedtouch router: laptops wireless, the desktop wired. The communication is ok in both directions for: - XT-laptop and XT-desktop - the XT-laptop and the Vista-laptop I can access the Vista-laptop from the XP-desktop. But I cannot access the XP-destop from the Vista-laptop. In network places on the vista-laptop, the pictogram of the XP-desktop is shown, but it cannot connect. XP-desktop and XP-laptop have the same XP-version. On all three computers the windows firewall is running. Shutting down the firewalls does not help. There is no McAfee firewall active. User accounts on XP-desktop and XP-laptop are the same. Changing passwords, including using blank passwords, does not help. Why can the Vista-laptopaccess the XP-laptop but not the XP-desktop? I would be tremendously happy with any help. Thanks, Paul

Hi When you say "it cannot connect" do you mean it stalls or it gives you an "access denied" error?Do you have anything shared on the Xp-destop?

Hi, With 'connect' I mean the access denied error 'you may not be authorized'. The sharing of folders on the XP-desktop is the same as on the XP-laptop: c; and below is shared. thanks in advance Paul

Hello Paul, Thank you for posting and sorry for reply delay! Please let me know if you have tried to ping Windows XP-based desktop from Windows Vista-based laptop, to see if there is a connectivity issue due to the transformation between wireless signal and wired signal. Please confirm the exact error message again. Thats important for further troubleshooting. Thanks for your patience and cooperation! Regards, Lionel Chen Microsoft Online Community Support

I had the same problem the other day; the only thing I did that I think may have sorted it was to set the two XP machines with a fixed IP address, within the APPIA (192.168.1.x) range. Vista I didn't get to when they all came up on each others network neighbourhood. Paul F
