I am running WIN/2003 standard. Using IIS, have 2 virtual websites.

Default website disabled
Admin website disabled
"Main site" Port 80 = works fine
"WebFOCUS"Port 82 = error below:

Cannot find server or DNS Error

Using 'netstat -an |more' I can see the following:

TCP 0.0.0.0:80 0.0.0.0:0 LISTENING
TCP 0.0.0.0:82 0.0.0.0:0 LISTENING

I don't get it why I can see port 80, but not 82. Tried changing port number to 83, 84, etc... no luck.

If I create a new virtual website and point to some random port, 882, all is fine, but I don't want to move all my webaliases to the new site....

Any ideas?

Where are you seeing "Cannot find server or DNS Error"? Server side or client?

Hard to understand why it woud happen on the client. Usually I just get the usuall "Page cannot be displayed".

If it is in server logs then you are probable trying to log client host names (instead of just the IP address) and you haven't configured it to point to a dns server. It is trying to do a reverse dns lookup on the IP address to find the name. But if you haven't pointed it to a DNS server it will error out.

Just guessing. I am not an IIS guru, though I once fixed a problem that sounds the same on a Lotus Notes server.

Turns out I had an ISAPI filter that was trying to be loaded, but got errors, and crapped out IIS... not sure how it got loaded, but once removed, all seemed fine.
