5 new IP's to assign.

I need a little(maybe a lot) of advise on assigning 5 static IP's to newly built servers, running(windows7). I have 5 new static IP's from my provider, and a new connection, with a new modem/gateway. According to most everything I have read, assigning a static IP to a machine through network and sharing center is fairly easy. For most versions of windows, it the same setting, Tcip4, then manually add IP.
But my machine doesn't show up as that IP. Reset the router, and now my IP is showing to be Comcast's homem office node, or whatever.
Any Ideas on what could have caused that?
Obviously I call comcast, and get a woman who's reading from her monitor. And blatently admits having no knowledge of windows 7. Wonderful tech support!!

You need to make sure that DHCP isn't enabled in your routers control panel. Although I'm not sure what kind of router Comcast is using so I can't give you specific instructions on this. It usually works best to assign static IP's in the routers control panel but it should work either way once you turn off DHCP.

I was acctually able to have both. Turned out that Comcast did not upload my IP's to the modem. I have the IP's set per machine now, after DIS-abling TCip6, which gets in the way of TCip4. And manually assign them. In each machine. Now they are working, and have DHCP on. I was under the impresiion, that wouldn't work, either. But I disabled it, and enabled it. And have full functionality either way. Thanks for the help though.

In default, the IP4 & 6 are "in use" so to speak, they're both enabled , well by MY mobo's LAN controller they were. Even on 2 other machines, Mine has win7 ult., 1 with win7home, and another with win7 Enterprise. Tehy all worked the LAN controller the same way, automatically enabling the TCip6, to obtain automatically, it was only when I dis-abled Tcip6, did the TCip4 static address, actually work. The gateway/modem , or my PC, one or the other was conflicting. Though mere observation I noticed above the TCip4, the TCip6 enabled through LAN/Properties. I spent 2 days, and nights on this, and after TCip6 was disabled , the static IP's set fine. And now show accordingly. Rather weird, I thought as well, but that was the actual problem.

I'm using win7, because I could not get win server 2008 to do anything, other than install. I am ignorant to the use of that software. I installed it 20 times, tried to so much as display a simple web page- to no avail. Win7 has everything I need to be used, like IIS. I got nowhere with that winserver software. I didn't have the time to learn it before installation tech's arrived to install Cable. I have a machine to use for practice, but 2 out of 5 new power supply's blew, from a Tiger/USA Comp/Direct sale, going on. I will try win server again soon.

IIS works fine with win7, and server 2008. Except I have major issues getting a webpage, to display. A subject that I am a little sore over, lol. I spent 2 weeks trying to make this software work. i never acctually got a database started. From Mysql, to Joomla, I tried all kinds of programs. trying to understand what each program does is quite the feat. I have had no training on any software of any kind. I build PC's for a hobby. I'm a gamer. But just getting a simple game server online was interesting enough, to want me to start a few webpages. I have domains, now. But being able to use them is still a ways off. Understanding something as simple as databases are enough trouble atm.
