Netbios Issue


A client has four computers (windows 7) and a Netgear FVS318G router

One of them is sharing files to the other three

From time to time the other three, or less, seem unable to reach the sharing PC

It doesn't appear in the network neighbourhood

When you reboot the sharing PC things return to normal

I switched all PCs to use static IPs, and checked that Netbios or TCPIP is enabled

The issue continues to manifest itself

any ideas ?

Two things just to ckeck that I have found sometimes upset the proverbial apple cart. In the network adapter properties is the TCP/IPv6 protocol enabled and active? There seems to be some dependancies now on IPv6 even though the protocol isn't employed in most cases (as far as I know).

I think if you take a system out of homegroup status, public network is specified instead of private. That's the way it worked on my system at least.

The only other thing I can think of is intentional altering either by antivirus/firewall/network configuration software or by malware.

This all looks like a Master Browser issue which may not be terribly limiting at all.  The list of computers in the Network Neighbourhood or, simply, Network comes from one of the computers which has been elected to be the Master Browser.  If the Master Browser computer is turned off or disconnected from the network then an election determines which remaining computer will take that role.  This process, regrettably, can take over half an hour.  During that time, the Network won't be fully populated.

Nonetheless the computers aren't unreachable during that time.
One can RUN: \\[ipaddress] to see a computer's shares.
Alternately, if name service is running with NetBIOS, one can RUN: \\[computername] to see a computer's shares.

Sometimes it pays to set a computer to NOT be in the election and NOT be the Master Browser .. every.
