How do I increase the computer name in a workgroup environment?

The original name was wks-wnxp-01908 and I changed it to :

WKS-WN8-TECH-01908

but when I go to:

!!
it shows up as:

!
How can I get it to show the entire name, as it is important for the organizations naming scheme. I didn't know there was such a limiting factor in the name. The last three characters are omitted.

Your expert advise is appreciated.

NETBIOS is limited to 15 characters for the computer name.

The limit on the workgroup name is part of windows. So then put the intelligence in the name near the beginning.  

I have not had to be concerned with the workgroup name length at any time.

thinkpads_User,

Respectfully , I was not referring to the Workgroup name , but the computer name.

Thank you PowerEdgeTech for the clarification.

I didn't know the limit was 15 chars.  Is there no way around the NetBIOS limitation. I will look at your link, but the points are yours.

The link doesn't provide a workaround - it is just documentation from Microsoft of the limitation in NETBIOS naming.  Longer names are recognized/usable in DNS, but there is no way around it that I know of for built-in Windows network discovery items like in your image.  You might be able to change administration of NETBIOS in your IPv4 network settings, but NETBIOS is NETBIOS, regardless of which device is handling it, so it likely won't help you at all.

The real problems will come when you have multiple machines in that "group":

WKS-WN8-TECH-01908
WKS-WN8-TECH-01909
WKS-WN8-TECH-01134

Then will ALL show up in NETBIOS detection to be WKS-WN8-TECH-01, causing naming conflicts and all sorts of headaches.
