Insert the following deny udp any any range 135 139 deny tcp any any range 135 139 in the access-list you're using to filter incomming traffic.

It depends on the IOS you are using. If you use one of the latest, something like
no deny udp any any range 135 139 no deny tcp any any range 135 139
should work. As a general hint, it is a good practice to only permit those you are expecting and deny all other.
