Network works, but no internet

[Guest]

Here is the situation: We hooked up 9 new PCs with WIN XP PRO into and
existing network at a hospital. We used a Linksys 16-port Switch. There are
three existing PCs (all have Win XP Pro as well) on the network which brings
us to a total of 12 PC in all. The issue we are having is this. The 9 New
PCs, when hooked into the network and given the proper IP, gateway, DNS, etc.
will network and see one another and share data fine. However, They will not
access the internet and they will not see the other three existing PCs that
were previously on the network. They all have the same workgroup name, and
are on the same IP sequence, etc. Here's another thread for you. The three
existing PCs will see each other, access the internet, and seem to have no
problems. Now, we have tried different IP sets, Different Workgroups,
different switches, different Network cards, all with the same outcome. What
could we be overlooking here and what else can we try? Thanks for your time.
