ok ill try and explain this....ok here goes my main pc...which i use i have set it up to share files over the network...i could never workout how to set up using passwords so i set it up with the option no password in network and sharing....every thing works fine most of the time we can log on to certain folders on my pc i have allowed and given permission...now here is the problem recently every now and again when i try to log on from either a pc or media box..ie asus o!play it sometimes asks me for user name and password even though i have password switched off...if i restart my pc i can connect again no probs without getting asked for a user and password...has anyone got a idea why it does this as i cant work it out ....thanks
