I recently changed from a static IP with Shaw (Broadband) to Telus

one is set to dynamic.... how should this look? Thanks Kevin

You should have a router/gateway/firewall appliance between your
network & the ISP's modem/router.... it's more secure, and you don't
have to change anything much inside your LAN when you change ISPs,
etc. Your WAN-facing NIC shouldn't have a public IP on it or use a
PPPoE connection, which is what ADSL generally uses. Even a cheapo
Netgear/Linksys will do this for you more neatly.

Your DNS forwarders should be configured to use your actual ISP's DNS
servers. Configure this in the CEICW (or in the properties of your
server in your DNS config MMC). But get a firewall appliance
first....even if you use ISA, which you don't mention.

I do have router, I don't use ISA., one of the things that my ISP has
told me is that they do change there DNS servers so it may not be a
good idea to use the current ones.Or should I just change them
anyways? (these are the one that are list with the static IP right
"64.59.135.XXX".

You can just change the forwarders in your DNS server (administrative tools
| DNS | right-click/properties on your server). But your ISP's comment is
curious; why would they be changing their DNS servers with any regularity?
I'd hope they would notify all their customers in advance, and that it would
be a rare occurrence.
