I am unable to access the internet on a Windows 2003 Server DC using a static ip.  when I change the ip I am ale to get to the internet.  But not with the original ip.

 For example:  NO Access to internet
IP 192.168.1.200
SUB 255.255.255.0
GW  192.168.1.1
DNS 127.0.0.1


 For example:   Access to internet
IP 192.168.1.201
SUB 255.255.255.0
GW  192.168.1.1
DNS 127.0.0.1

Any ideas??

do you have a firewall with rules set? the rules could be set to restrict Internet access to a certain range of IP addresses. the new ip address maybe outside the resticted scope of ip's.

Nothing in the firewall.  This all of a sudden happened....I changed the ip and it works. But I reall want to use the orignal due to network data access.
so are u saying that the Internet used to work with this ip before i.e. th one not working now? is there an ip address conflict with another device? are you able to access network resources with the IP in question? can you ping the gateway?

Check the log on the firewall to see why the Internet is not going through.

Yes to all .....no ip conflict.
I would try the following:
1. Check the logs in event viewer for any errors.
2. Pay attention to any DNS errors.
3. Check DNS entries to make sure they are correct.
4. Try and flush the DNS on the DC i.e. ipconfig /flushdns
5. Try and recreate the DNS if all else fails.
check you hosts file

with IP 192.168.1.200 set, type this on a command prompt:
ipconfig /flushdns

also, try this:
gpupdate /force

if you have a hardware firewall check it too.

all this should be tried before szichen last suggestion.

check this how-to I wrote about internet explorer problems. some of them apply to this also.
