Hey guys I am having a strange issue with my Network which has windows 7 and XP computers. Heres the issue : Ive a windows 7 computer where my POS application is installed on with a basic folder Shared with no restrictions, means that everyone on the network can access it but after some times all XP computers cant access the specific folder anymore and the only way I can fix it is by rebooting the windows 7 computer (The one with the Shared folder on). The other strange thing is that all other windows 7 computers can still access the Shared folder, only XP computer cant. It happens really randomly and ive not been able to see what happen just before the problem appears, it seems that it just crash randomly without any specific actions from the XP computer's user. There is a total of 7 computers on the network with only 2 windows 7 so ive 5 computers with XP and all 5 cant access the computer. The ping to the windows 7 computer still respond but there is no way to access it from the network like \\computername or \\computerip it says that the computer doesnt have the rights to access it. If you need more informations, just ask and ill do my best to give you more. Sorry for my english, it's not my first language. Thanks in advance for your help.
