samba - Jun 2002 - Lot of connections

Hi, i'm using samba 2.2.3a on a RedHat 6.2 server. There are 3 NT4 and 2 2k
servers connecting to this samba, the thing is when i use the
'smbstatus'
command i see a lot of connections from the 2k servers and just 1 or 2 from
the NT4 servers. Is this a win2k issue or a samba issue?.
Thanks ,
