I have three laptops: lenovo A (win 10 home), lenovo B (win 10 home) and old HP nx6310 (win XP, SP3, PRO). I try to connect them together via ASUS RT-N12E, wifi router. I can connect to internet from each laptop. I can connect at least one way between win 10 systems. I can ping between all 3 laptops. But I cannot connect from win XP to win 10 and vice versa. I tried many things, so maybe something went wrong. I use same IP XXX.YYY.ZZZ address for all laptops, I have same work group. I even see Win10 laptops from windows XP. (Or in previous restart I saw XP machine from windows 10). But when I click to (win 10) machine in workgroup it writes (I try to translate):
"Item \Laptop_with_win10 is not accessible. You have insufficient authorization for access to this item. Turn to your server administrator and check your permission.
Path in network was not found.
(OK)
"
(remark: windows 10 uses wifi, XP is on cable, but it can be change to wifi also.)
Have you got any suggestion or idea what to do?
remark2: I normally log in to XP and win 10 with administrator rights, and use widows account. One small thing happened with my experiments that XP log in with window form instead of whole screen with icons. I do not know how I did it.
