I suggest not, normaly dns is used for that, by the setting 
"dns proxy = yes"  ( the default )
But you must be sure your dns setup is good. 

>From man smb.conf 
dns proxy (G)

Specifies that nmbd(8) when acting as a WINS server and finding that a
NetBIOS name has not been registered, should treat the NetBIOS name word-
for-word as a DNS name and do a lookup with the DNS server for that name on 
behalf of the name-querying client.

Note that the maximum length for a NetBIOS name is 15 characters, so the DNS name (or DNS alias) can likewise only be 15 characters, maximum.

nmbd spawns a second copy of itself to do the DNS name lookup requests, as 
doing a name lookup is a blocking action.

>>  Default: dns proxy = yes

You can increase the WINS TTL if needed. 
But normaly this is not needed. 

Anyway, what im missing here, is, is this a ADDC or member server setup. 
And which node type is set for the computers. 

Often in dhcp is type H used. (hybrid) which tells the computer to do the NAME => Ip resolving by asking  WINS first and then broadcast. 

And remember, of needed to flush the local (PC) NetBios cache. 
Check with nbtstat -c to see if its all correct. 
nbtstat -R ( or nbtstat -RR ) to flush local cashe. 

And editing tdb files .. 
tdbtool --help
