weird round robin behaviour

[peterve]

I have a NT4 DNS server,
it contains 2 records with the same name, but with different IP addresses
If I ping to the fqdn from a NT4 machine twice, I get another IP address every time I ping (round robin)

But when I ping to the fqdn with a Windows 2000 machine, I always get the same IP address...

what is wrong here ? ---------------------------------------------------------------------
I have not failed, I've just found 10,000 ways that don't work

per MSTechNet Q154442:
"Most HOST utilities (FTP, Telnet, and so forth) make a separate request to DNS each time an attempt is made to resolve the name. The round robin feature of DNS enables DNS to return the IP addresses of the name in a different order each time."

This is what you already know of NT4.

per MSTechNet Q177883:
"The latest version of Dns.exe for Windows NT server introduces a new feature, LocalNetPriority, that attempts to return Host resources that are local to the requestor instead of merely responding round robin."

That is probably what you're experiencing here. Q177883 goes on to tell how to disable the LocalNetPriority setting:

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters

Create a new value using the following information:

Value Name: LocalNetPriority Data Type : REG_DWORD Data : 0 (0 = disabled, 1 = enabled)
