A few months ago we changed ISP's and therefore got new IP addresses.  When i try to go to our Outlook Web Access from outside the business it is resolving to the old address. So if our url to outlook web access was
http://owa.somecomp.com that is taking me to http://uuu.xxx.yyy.zzz/exchange
where uuu.xxx.yyy.zzz
is our old IP.
if i ping owa.somecomp.com the ping resolves to the correct new IP
if i go to http://aaa.bbb.ccc.ddd/exchange where aaa.bbb.ccc.ddd is the new ip OWA comes up fine.
Seems like something was missed in the conversion just not sure what

Do you actually see xxx.xxx.xxx.xxx/exchange in the address bar of your browser, where the xxx.xxx.xxx.xxx is the old IP address? If so, then it sounds like there is some sort of forwarder set up to forward requests to that old IP address.

You say:
>>> So if our url to outlook web access was
http://owa.somecomp.com that is taking me to http://uuu.xxx.yyy.zzz/exchange <<<
Did you omit the /exchange from the first URL you mention deliberately? If so, do you have some sort of script running which is redirecting requests to the root of owa.somecomp.com to the /exchange directory, but it happens to have the old IP address hard programmed in?

Also, just to check, can you go to Start, Run, cmd, OK. Type nslookup owa.somecomp.com and make sure that you get the correct IP address come back in the second part of the response.

Just to clarify, when I say "forwarder", I actually mean some HTTP or ASP/PHP page is being initiated and is manually redirecting to the old IP.

yes i see the actual ip and the page cannot be displayed obviously since we do not have that IP any longer.  I am looking for a forwarder now
Thanks
