Wed W2K Professional Question of the Day

|  And today's poser is ....
Q26. Alison is the System Administrator at the Flower Farm Collective. The Flower Farm Collective is looking at upgrading from the current NT4 Domain to a Windows 2000 Domain. In the western arboretum, there are five NT4 workstations that are to be upgraded to Windows 2000 Professional.
These Windows 2000 Professional computers will be set to register automatically with the new Windows 2000 DNS server. Because of the freewheeling atmosphere at the Flower Farm Collective, in the past there was no naming convention. Each member of the collective was left to name their own workstation as was their imagination's fancy. Alison is concerned that because of this, some of the NT 4.0 NetBIOS names may not be valid DNS host names. This will mean, most likely, that some of the computers must be renamed so that they conform to the character set specified in RFCs 1123 and 952.
Which of the following computers must Alison rename to conform to these standards? (Choose all that apply)
A. carcenoma
B. 31337
C. green.thumb
D. 1totestit
E. _omegasupreme

| DNS doesn't recognize _ (underscore),.,1
so i'll go with denis's answer.  | |

| As I understand it Win2k will replace any Underscores it finds in workstation names with the dash (-) during installation, although quite how this works with regard to DNS and what will be a (-) at the beginning I am unsure.
as to the others.... B, C and D will need to be changed I believe. | |
|
| "A , B ,D " will be my choice.
Less than 10 days.............
 | |
|
| Once again !!!
I don't read the question properly ?????
Always in a hurry to answer !!
Rename " C and D "
 | |
|
| Well!! Well!! Well!!
Rename "c and E " | |

| Ok just been checking up on rfc 1123 and found this
2.1 Host Names and Numbers
The syntax of a legal Internet host name was specified in RFC-952
[DNS:4]. One aspect of host name syntax is hereby changed: the
restriction on the first character is relaxed to allow either a
letter or a digit . Host software MUST support this more liberal
syntax.
Which makes me think that D would be valid.
However I then checked rfc 952 and found this...
Note that although optional nicknames are allowed for hosts, they are
discouraged, except in the case where host names have been changed
All this leaves me a little , could someone clarify this for me please ? | |

| Gonna go with b,c,e. BTW, is C "1 to test it"
or "1 totes tit"? | |
|
| Hi guys,
stepping out of the darkness of lurking and posting first time now...
I think only "C" and "E" has to be renamed.
I think to use only numbers for a DNS name is legit so B can keep it's btw "kewl" name. 
lardie:
RFC-1123 states that it relaxing the
convention of RFC-952.
So it's revising RFC-952.
That's the normal way to change a rfc (write a newer one that obsoletes or change portions of the older one and 1123 is younger than 952) or am I wrong ?
-> Network gurus this is your turn | |

And the answer is ....
Correct Answer: C and E
Original DNS names are restricted to the character set specified in RFCs 1123 and 952. It includes a-z, 0-9, and characters. In addition, the first character of the DNS name can be a number (to accommodate the needs of companies like 3Com or 3M).
Underscores are not recommended in host names as Windows 2000 uses underscores to designate a record as an SRV record. In addition, the period (.) has label separator meaning and should not be used. | |
