Target - Test Windows Name Resolution Process and Hierarchy being followed
ISSUE - Steps 6 and 7 (of section --> Windows Methods of Resolving NetBIOS Names) not being carried out
http://technet.microsoft.com/en-us/library/bb727013.aspx#EFAA
Setup:-
WINS Server - 11.0.0.111 / 8
DNS Server - 11.0.0.1 / 8
Two XP DNS Clients Exist
S1-xp-01 - 11.0.0.51 / 8
S2-xp-01 - 15.0.0.51 / 8
S1-xp-01 /etc/hosts contents excerpt:
15.0.0.51 s2-xp-01.s2.com
S1-xp-01 Details:-
1) As it's using WINS - thereby has Hybrid Node.
2) Using DNS Server - 11.0.0.1 / 8
3) Winsock - Service Provider - all values at default.
S2-xp-01 Details:-
1) Doesn't uses WINS Server listed above.
2) Winsock - Service Provider - all values at default.
Now, at S1-xp-01 Console, we try to resolve NETBIOS NAME "s2-xp-01".
Wireshark trace reveals that
1) First WINS Server is contact'd which replies with a Negative Answer.
2) Secondly, NBNS Broadcasts is carried out, which fails as s2-xp-01" is at remote subnet.
Now as per above documentation, our local client should consult /etc/hosts file, and the DNS Server, but no such activity is being carried by our client.
This might be solution, http://support.microsoft.com/kb/142309 | but this GUI interface is
not there at XP | might the RegKeys associated with this GUI option solve the ISSUE :|
So, how to get these 6 and 7 STEPS working ???
