Can't get to two websites
I need some professional IT help. I have 2 websites, 2 different servers, 2 different IP addresses, hosted by 2 different companies. Both sites we moved to a new server and given a new IP address. From my t1 line at work, i can't get to either one since the switch. From home, i can get to it just fine.
Can anybody give me ideas as to why i can't get to these websites? Would my network be blocking these sites? Maybe they haven't updated with the new IP yet. I'm not quite sure. On my network, i have:
Cisco 1400 series router
Cisco PIX 506E Firewall
Windows 2000 Server running AD, DNS, DHCP
I have done a tracert and ping on both of these sites. They both get through my ISP and they both hit the hop before the final hop. But for some reason, i can't get to that last hop to complete the connection. If i ping, they both time out. I have been on the phone with my ISP, Webhost, etc and they all say everything is fine. (even though i don't believe them.)

it could be that you have some old entrys in you c:\windows\system32\driver
Also check in your local DNS to ensure you don't have entries in there with the old IP addresses.

If this dosen't work try telnet to the ip address you resolved above.
->telnet XXX.XXX.XXX.XXX
or open your browser and type the address in the "address bar".
Can you see anything?
If not at this point you will need to find out why you are being blocked by the hosting site? Since you have already run a trace you know it's not your firewall stopping the traffic unless you are restricting all http traffic to the only the 3 old servers...
->telnet XXX.XXX.XXX.XXX

So the site resolves to the correct IP address, but when you put that same address in your browser, you get a page that is old? Most often that is just a matter flushing the cache of your browser, but in this case I doubt it.
Try and ping the name of the website...you won't get a response but it should resolve, and this may help us determine if you have a host file that could be in play here. If we determine that you don't have the site cached, and you don't have a local host file in use, then I'd start looking at the other places where you think it is working correctly, and just verify that using the same steps you are using at your work.

yes, the website did resolve correctly (to the new IP address). I keep thinking that i have the site cached somewhere. Either in my dns server, firewall, or router. But the odds are that if 2 separate websites change IP addresses and everybody else can get to them, then it is something on my end.
Can you telnet to the ip address as indicateda above.
Well, let's see if we can rule out your network.
From your internet router, try and telnet to the IP in question on port 80. If you get a connection refused, or other message, that is bad, if the telnet session connects (you may not get any kind of feedback that you've actually connected, you just won't get a message that you didn't connect, then that is good.
Of course, if you can connect from the outside interface, but not from an inside host, then that gives you something to look at.
Despite being able to complete a trace route against www.network-tools.com, ithat doesn't mean you'll be able to complete a traceroute against another domain. Not only do you have to allow ICMP, which apparently you do, the far side also has to allow ICMP as well.
Is there any chance you are using some kind of proxy server?

I apologize for not posting on this thread.
I am still having the problem. My ISP says everything is fine. I can get into the router, do a tracert and ping and they both time out. I also tried to telnet and that doesn't work either. Could it be my router? Does it store dns information?
I am not using a proxy server.
Thanks for all your help.

i was able to figure it out. I'll split the points to ITDharam and Joesmail for helping me.

It has been 3 weeks since the server and IP change. I would hope it would have propogated by now :)
If i go to www.network-tools.com and do a tracert, i can get to the last hop, so i would assume that icmp has not been disabled.
When i do the nslookup, i get this...
C:\WINDOWS\system32>nslook
*** Can't find server name for address 192.168.0.1: Non-existent domain
*** Default servers are not available
Server: UnKnown
Address: 192.168.0.1
Non-authoritative answer:
Name: website.com
Address: XXX.XXX.XXX.XXX
Aliases: www.website.com
192.168.0.1 is the IP address of my dns server at work. The XXX.XXX.XXX.XXX is the correct IP (the new one) of my website.
