Yes, I know how to disable Netbios. How do I determine if Netbios is needed on our network? With Wireshark, I can see a lot of NBNS requests going to one of our domain controllers. Is Netbios still needed for printing or network shares?

<div>
I've turned off Netbios on my computer. I'm going to leave it off for a few days to see if it breaks anything. If not, then it's probably safe to disable it on all of our client computers.

I'm using Wireshark to analyze traffic on our network. I see a lot of Netbios name service (NBNS) broadcast traffic to a server that no longer exists on our network. The requests look like this:<br />
<br />
24810 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1679.856442000 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.45.16.157 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.45.16.255 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NBNS &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;92 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Name query NB OLDSERVERNAME&lt;20&gt;<br />
<br />
The requests are all coming from our client computers. Some client computers are sending the requests to the correct server.<br />

What's the best way to stop the errant requests?

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
