There are many services listening on your network.  Which one are you talking about?  Note that disabling a network service will disable any programs that use it.

for example, turn off ports 137, 138 on UDP and 445 on TCP

That's not a 'service' issue, that is a firewall issue.  If you disable port 445 on the LAN and not just over the internet, you may have some problems.  You will need to check to make sure your network is still working after you do that.  Particularly file and printer sharing.

These ports are not open by default on win 7, maybe not even on XP, just undo your own actions to open them.

These ports are open on some laptops and closed on other laptops. if I control these network listening ports using group policy, where is the best place?

windows setting-> security setting->windows firewall with advanced security
windows setting-> security setting->network list manager policies
windows setting-> security setting->network access protection
Administrative templates-->network-->network connect-->windows firewall
or somewhere else?

windows setting-> security setting->windows firewall with advanced security ->for PCs vista and higher
Administrative templates-->network-->network connect-->windows firewall ->for xp or higher
Frankly, if you are worried about network security, kick out xp, first.

Problem with these policies: local admins might have configured exceptions already. Those can only be undone after identifying them via script, or, and this will be tough, by closing all ports ("block, no exceptions").
