Why mpiexec utility doesn't work with NetBIOS names ?

Dear Collegues,

I've got a problem with using mpiexec utility so that when I specify nodes in hosts list by their NetBIOS names rather than providing an IP-address for each host, mpiutility displays an error message that it cannot connect to a particular hosts and MPI program cannot be executed. For example:

mpiexec -n 4 -ppn 2 -hosts 2 192.168.0.100 1 192.168.0.150 1 myprog.exe - this works fine.

mpiexec -n 4 -ppn 2 -hosts COMP-PC,WIN-9MFH3O78GLQ myprog.exe and this causes the mentioned above error to be incurred.

What particular settings such as firewall or NetBT protocol I have to change to make mpiexec utility to work well with NetBIOS names

Thanks in advance.

Cheers, Arthur.

I found a solution of this problem. This is not actually an NetBT or firewall problem. Normally, I cannot use NetBIOS computer names since they're not specified in my DNS server settings.
