I have 2 PCs setup with the same version of Windows 7 Ultimate, both with wired connections to my BT home hub 2 router. 1 PC I have no issues with: I use windows explorer to network, and also access from work and mobile using both VNC and Remote Desktop. The other PC, as far as I can tell set up the same, I have intermittent connection issues. Sometimes explorer can't access the network, sometimes VNC can't access it, and (except from other network PCs) I can't seem to RD on to it. The internet is constantly working, and although I can't access using explorer, I can always see the PC, so I think there is something blocking access. I have turned off my firewall (ESET - windows firewall is disabled), and I have allowed the relevant ports for each way of access... I really can't work out what's wrong, and it's very frustrating... I left that PC on this morning so I could access from work, and nothing! Any help would be really appreciated!
