Windows 7 Pro - net view randomly gives error
Please advice anyone - I am lost... I use a Cisco E4200 as router/GW for my LAN/WiFi clients, and have PCs and NAS (WD Live Books) devices connected to LAN - and Laptops, Blackberrys and Playbook(Samba) connected to WiFi. There are NO firewall on the E4200. After a fresh start of all devices - things work as they should. a "net view" on my Windows computer shows all devices that I should see. In Windows Explorer, under Network, it correctly lists all the "computer" devices on the top, then Media Devices, Router and storage devices. Then - after anything from a few minutes - to hours - sometimes a day - devices starts dissapearing from the top of that list - They dissapear from "Computers" but are still listed under Storage or Media,.. AND - I can always ping all devices, I can connect to them with UNC path etc.. so connectivity is there... When devices starts dissapearing from the "Computers" section, I am unable to do a "Net View" from my Windows computer, only getting the error: "System error 6118 has occurred. The list of servers for this workgroup is not currently available..." but - still "net view \\hostname" will list all shares on that computer... A reboot of the Windows computer does not help, same problem.. The Only way to normalize the situation again, is to cycle power on the E4200 router. and things are "normal" again - until it happens again - after 3-4 minutes - or hours... I have spoken to Cisco about it, and they say that since I can still connect to all devices on the LAN, and NO firewall on the router is On, No Port blocking - No firewall at all - that it cannot be the Router - but must be a Windows problem... I have met the wall here... I would have thought that - since a reboot of Windows computer does not help, a reboot of router does not help - but a full Power cycle of the router Works.. that it should be a router issue... But - I have sometimes managed to "fix" by doing a full reset of TCP stack on the Windows, rebooting and setting IP again... It almost seems as if Windows is filling up some internal cache/routing tables inside the Router, filling it up with problems... Things are working without the Network Browser able to populate the Computers on the Network table, but - it is irritating not being able to see all the network connected computers when I need it. I have tried most things - including disabling Windows own firewall - but - same result.. I have change workgroup name on all devices - same result I don't have any Homegroup defined.. TCP/IP v6 is disabled Only one network adapter enabled Static IP configured MTU on router set to 1365 and WHAT can cause the "net view" to suddenly stop? and WHY is it "fixed" only after I power cycle the router? Please jump in anyone, any suggestions are welcome... I want to have this fixed...
