The legal characters available for tcp host names are:
- a-z
- A-Z
- 0-9
- – (hyphen,the underscore is illegal)
- . (dot)
domain name combination configured at install follows NetBIOS conventions. When
you install tcp/ip, the default tcp protocol machine name will default to the
NetBIOS machine name. It can be left the same or changed. Each protocol can have
a different machine name. If the NetBIOS machine name has illegal characters
(for ip, legal for NetBIOS) such as the underscore, they will be converted to
hyphens.
