One server with two NICs.
Assigned two IPs to these two NICs and all applied to the same WINS server.
I wonder maybe the wins server will think that two different computer use the same NetBios name?
Can it work properly? or what can I do to avoidthis problem?

From Technet article Q198644:
"The error message in not generated by Windows NT Server itself. It originates on the environment's WINS server, which now contains a database entry of for that server. This indicates that the server is registered with WINS and that WINS believes it is a single NIC system, and is, therefore, reporting this as a duplicate name on the network.

To resolve the conflict, add primary and secondary WINS addresses to the second NIC (these should be the same WINS addresses that are listed on the initial NIC), and then restart the system. This will force a reregistration of the system with WINS and the registration will change from UNIQUE to GROUP, and will be labeled Multihomed. The error message will cease. "

So go ahead and configure both adapters to use WINS. It will work better that way.

Hope this helps.

You could either add a multihomed record in the wins server and set both nics to use that wins server or hope that wins does that for you. For me it did. You could set just one nic to use wins and the other one insert it in lmhosts files accros the network (not recommended).

If you configured the nics right just add a multihomed record in wins and it will work just fine. Here is a example for windows 2000 server that runs the wins service:
Type the following commands in command prompt:
netsh
wins
server \\SERVER
add name Name=MHPC RecType=0 Group=3 Node=3 IP={192.168.0.100,192.168.0.101}

where MHPC=the netbios name of the multihomed computer, SERVER=the netbios name of the wins server and the ip addresses you must set are the ips of the multihomed computer.

the easy thing to do it, unbind the wins from the 1st nic, and remove the address from the tcp/ip properities. Only use wins on the nic you really need to. if the nic needs to use the wins server it will route to the second nic.
