Windows 8.1 Event ID 4319 (NetBT) Causing Lost Connection to Network:

Hi. I'm running Windows 8.1 Pro in a domain environment and am noticing at times I'm losing my connection to the network.
If I have a network drive opened and am doing something else, a few minutes will go by and I'll see a message saying I lost connection to the network.  The connection appears to be fine. I'm connected by LAN.
I've turned the wireless connection on my laptop off to try and narrow down the issue.
The event in the event viewer each time I lost connection is as follows:
Event ID 4319 - NetBT
A duplicate name has been detected on the TCP network.  The IP address of the computer that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.

I'm not sure what that means. I'm the only one in the company running W8.1 so I don't have much to go on here.
Any help would be appreciated.

The error indicates that your machine has the same IP address as another device on your network. This causes a conflict resulting in a loss of connection.

There's a number of possible causes that would result in this:

Your machine and another device are set to static IP addresses.
You have 2 systems on the network (i.e. router and server) giving out DHCP and have given out the same IP address to two different devices.

I would start by getting a list of all the devices on the network and their IP addresses then from there identify which is similar and either change that or change the one on your system.

Do you have other devices connected to the network?i.e your printer, server etc.

There is conflict of IP on your network.

Its not related to OS, its depends on computer name in same network. That the reason getting  Conflict error.

It means, that you have another device on your network with the same name like your computer and that your network adapter does not like that. The ipaddress is in the event data, you should tell your network admin to sort this out, if you cannot understand what the message is telling you, he is the right person anyway.

I've went ahead and renamed my computer so we'll have to see if it happens.
I'd get the message/error at least a few times per day so I'll know by the end of the day if changing the PC name helped.
I'd like to know how this happened though. Every computer is manually named by me when I configure them and add them to the network/domain.
I wouldn't have added the same computer name twice (especially my OWN).

My computer doesn't have a static IP.  And even if it did, I thought the IP address conflict message is different than the one I'm getting.

I just checked all of the IP addresses being assigned via DHCP and my computer is only listed once (LAN and WLAN).

you should only have 1 network adapter connected to the network at any one time you have it in both LAN and WLAN .. and so the network doesn't know which path to use 253 or 218

I'm running Windows 8.1 Pro.
I am connected via ethernet cable and am also connected via wireless.
I can't for the life of me figure out why when I click DISCONNECT from the wireless AP I'm connected to, it automatically reconnects.
I've already went into every setting I've seen and short of turning the wireless on my laptop OFF, I'm at a loss.
Could you solve it?

Yeah, I had to uninstall the Intel PRO/Wireless software. Now the wireless has permanently "forgotten" the access point.
