Help!

I work at a small company and for the last 4 days our small network (4
computers!!!) could not and still can not get online, I told my boss it might
be a DOS (Denial of service) attack. all the files seem to be OK but I just
cant get donline, Question, how do you recover from this type of attack??

The OS's are Windows ME and windows 2000 the other boxes are linux (Mandrake
and RedHat) all connected via a router. My friend told me to just reset the
router connection (internet connection) and all will be well, but I just want
some expert advice before doing so. I hope to hear from someone soon.
