Well, I'm no expert, but here's what I found:
This registry entry works for both Windows XP and Windows Vista
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\DNSClient]
"AppendToMultiLabelName"=dword:00000000
HKLM\Software\Policies\Microsoft\Windows NT\DNSClient\AppendToMultiLabelName
Type = DWORD
Data:
- 0 (Do not Append Suffix)
- 1 (Append suffix)
If the registry entry is not present, the default in Windows XP is 1, and 0 in Windows Vista.
Note: This registry changes and its effect apply only to the ping command, they do not apply to the nslookup tool. This is because nslookup contains its own DNS resolver and does not rely on the resolver built into the operating system (DNS Client). The DNS (multi-label) query packets sent by the nslookup tool will append the domains listed in the suffix search order irrespective of the registry key settings mentioned here.
