I use RH8.0 to host 1 site and everything has worked OK for about 6 months.

Last night I was surfing my site and SOME pages cameup with an error message of the following "Cannot find server or DNS Error"

now I say some because it means just that SOME.

I have about 5 htm pages in a directory 2 do not work, 3 do.
I check to make sure the files are still there and they are but I still cannot view them.

Anybody ever had this problem

I guess I need a lot more information than you have supplied.

Are you connected to the Internet?
How are you addressing your webserver? ( localhost, 127.0.0.1, mymachine, mymachine.mydomain.com )
Do you run a DNS server ( BIND is most common)
If not, what are the contents of your /etc/hosts file?
What browser are you using? Are you sure the browser is hitting the server everytime you access a certain page? In other words do you have caching turned off?

Chances are that the 3 pages that 'seem' to work are pulled from the browser's local cache.

Thanks for the reply.

I am connected to the internet through a cable modem

I have tried looking at http://ipnumber and http://www.domain.com, and localhost same result.

I do not run DNS or BIND DNS is managed i think by my isp

/etc/hosts = "127.0.0.1 myserver localhost.localdomain localhost"

I have tried IE Mozila and Netscape and I have had freinds try to access all 5 pages and they get the same 3 pages to work.

I have posted 2 new pages to see if catching was taking place however I could read the 2 new pages.

Let's back off a bit and look at what's going on here.

Of the 5 pages you have...

1) how many are static HTML and/or accessible directly? ( like if the first page POSTs to the second page, that would make the first page directly accessible via a GET request... but not the second page because you HAVE to go through the first to get to it)
2) how many of the directly accessible pages are indexed?
3) If the pages that dont seem to work are indexed ( hyperlinked ) from another page that works, are you sure you are using the right domain in those links?

You are welcome to send me your IP number or domain name over email or PM so I can take a quick look. That should avoid a lot of going-back-and-forth.
