can anyone shed some light on this for me please I have 3 pcs networked together, through a router. they should all be able to share files and drives with each other, and 2 of them can, but the 3rd pc can not have it's shared files opened by the other 2 but it can access their shared files. This was not always the case it has only stopped granting access 4 weeks ago. I started the affected pc in safe mode and logged on as the administrater then the other pcs could see the shared files, but once logged on as normal again back to where we were. Any help wuold be greatly appreciated!
