Clearing the DNS cache on our domain?

[shakatak]

I'm having a bit of a problem with our cache or maybe it's something more complex, which I am not sure but here it goes.

Our domain is hosted with an offsite company and shows up as

http://www.ourcompany.com

which is correct when typed outside of our company network; however, when we type up

http://www.ourcompany.com

within our internal network it shows up as

http://www.ourcompany.webhost.com.

I was told that I would need to clear the cache which I believe I have done correctly or maybe this is the wrong solution. Can someone give me some guidance on this? Any help is greatly appreciated.

There are a couple of possibilities why this is happening:

1. Assuming you are using an internal DNS server, it has an incorrect record for

http://www.ourcompany.com.

Try an 'nslookup

http://www.ourcompany.com'

and report results.

2. You have an incorrect entry in your local hosts file. Open it up in a text editor, and see if there is an entry for

http://www.ourcompany.com.

I added our company's IP and the host name in the HOSTS file but I still have the same problem. I'm not too familiar with nslookup or which record I would need to modify in DNS. Would this be an A record?
