Hi, In our workgroup network with more than 25 PC & laptop includes Windos XP, 7 profesional, Vista home premium. Now the prob is I can't access shared folder on XP prof. from vista home prem PC. I have checked firewall & NTLM version on both systems. Can anyone suggest any solution? Best, SanBest Wishes, San3d

Hi San, Temporarily turn off the firewall to check if it works. What’s the error you got when you cannot access the shared folder? Are you running Windows XP with Service Pack 3? Please also refer to this: Network Map in Windows Vista does not display computers that are running Windows XP Regards, MiyaThis posting is provided "AS IS" with no warranties, and confers no rights. | Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
