I'm looking for some help before the PC ends up going out of the window!
I have been using the PC / network set-up quite happily for a few years now, no problem, until yesterday when my LAN turned from working to "Unidentified network", and since has been OK / errors without any reason.
My set-up is 2 PCs (windows 7 pro), connected to 1 switch, which is connected to a ring-main adaptor, which is connected to the broadband router.
I have done all the usual sets of powering everything down, and back on again, which doesn't make a difference.
I have tried a different switch, again no difference.
I have tried removing the switch and connecting the PCs together directly, no difference.
I then looked at the ipcong stuff.
When I do....
ipconfig /release I get "an error occurred while releasing interface loopback Pseudo-interface 1: system cannot find the specified file"
ipconfig /renew the cmd just stalls and doesn't appear to do anything.
ipconfig / flushdns which appears to work, but makes no difference.
netsh int ip reset reset.log appears to work, but makes no difference.
netsh winsock reset appears to work, but makes no difference.
At the moment IPv4 is automatic, but have also tried manually typing in IP address, but no difference.
I have also uninstalled Hamachi, but makes no difference.
I'm currently connected to the internet via teathering with my mobile, so I know Windows / software is working.
Does anyone have any suggestions what might be the issue, and how to solve it? I've searched the net for hours and tried everything I've found, with no luck. As I say the problem comes and goes, but with no pattern. It's not like it even happens after a restart.
Any help would be really appreciated!
