I have 3 computers on the network all running windows 7 ultimate. Only 2 of the computers are able to access all 3 computers and share files, but on the 3rd computer I am unable to access either of the other 2 computers.
I am able to ping my router and all of the computers from all of the computers.
I have the same workgroup on all of the computers.
I have tried turning the 3rd party and windows firewall off on all of the computers
I have made sure I am on the same subnet and gateway on all of the computers.
none of the netbios names conflict
file sharing is enable on all of the network adapters
share permissions are set to everyone with full control
and I have set my local security for networks to "Do not allow anonymous enumeration of SAM accounts and shares disabled andDo not allow anonymous enumeration of SAM accounts enable"
So I am at my wits end as to what I would try. Oh yes, all three computers where working perfectly once I am not sure what happened, I mainly just use the computer for video and haven't changed anything on it, perhaps an windows update could have done something but I am not sure.
