[Samba] Question on Samba 3.07 compared to 2.2.6

[Adi Nugraha]

Hi, I was just using samba 3.07 as a file sharing server, but the
workstations that use Win 2K was unable to access the shared file (took to
long about 10-15 minutes just to view the files) where as workstaions using
linux was using the shared file as usual, so we decided to go back to samba
2.26, and it worked for Win 2K, anyone know why this happens, any
configuration that i might have missed ?, BTW I'm using basic file sharing
server configuration taken straight from the Official Samba howto.
