We provide support for a small business that only uses 4 pc's. Normally they all connect to the same network and can detect and share files without issue.
However, they've contacted us to report that 'recently' (nice and vague... could be anything between 1-4 weeks since they noticed issues) one of the computers ( a laptop used both in the office and at home) has stopped being able to detect any devices on the network. They're connecting via a public network and the other machines can still detect the offending unit without any problems.
It's using windows 7 (entire office is w7 or vista), LLTD protocol is enabled, as is network discovery. It can ping the other devices on the network, I can map a network drive and get the files, but it will not detect other devices in the network and sharing center and cannot sync files as it claims network is disconnected.
This has me thoroughly confused now and any advice would be appreciated
