How to get correct IP address with computer name?   

Hi,

I have problem querying the correct IP address with computer name in the 
following scenario:

Two computers (Windows XP SP2 professional) involved:
IP addresses are managed by DHCP Server.
name        IP
ComputerA    149.245.176.170
ComputerB    149.245.176.194

ping ComputerA on ComputerB, I get 149.245.176.170, it is correct.

Switch ComputerA to another network, then it is assigned 149.245.179.175.
Again I ping ComputerA on ComputerB, I still get 149.245.176.170 and 
timeout.
I also tried  \Microsoft SDK\Samples\netds\DNS\DNSQuery sample, but it 
returns error code 9003 on ComputerB.
Although I can't find ComputerA by DNS query, file sharing is still working, 
ie, I can access \\ComputerA.

How can explorer.exe find the right machine when DNS does not work? Can I 
implement the same feature?

I hope I have made my problem clear.

I have tried "MicrosoftDNS_WINSRType" and got "0x8004100E" error at the 
second line.

strComputer = "."
Set objWMIService = GetObject ("winmgmts:\\" & strComputer & 
"\root\MicrosoftDNS")

I want to get IP address of ComputerA on ComputerB programmatically, no 
matter via WINS, DNS, DHCP, ADSI, WMI or something else.
Thanks a lot for your attention.
