DNS/ISA error on Intranet web

Guest

Webserver IIS 5.0 Windows 2K Adv Server fully patched
ISA Server is Windows 2000 Server fully patched and is my gateway server.
DNS and DHCP are running on a seperate W2K member Server

I have no trouble with any client machines on the internet. However I seem
to be having a DNS issue on the LAN Intranet. I have several web apps I have
developed for letting users enter data into SQL Server. The Apps work fine,
but I cannot hit some of them using the friendly URL. I have to use the IP
address. The error I get is as follows:



11004 - Host not found
Internet Security and Acceleration Server
--------------------------------------------------------------------------------
Technical Information (for support personnel)

Background:
This error indicates that the gateway could not find the IP address of the
Web site you are trying to access.

ISA Server: starlite-isa.starlitetheatre.local
Via:
---------------------------------------------------------------------------------------

There are other local web apps that work using the friendly URL. I have
tried using a different DNS server but I get the same error. I have checked
the Resource Records in DNS and not found any that are pointing to the wrong
addresses. Any ideas would be appreciated. Thanks!

Hi


This seems related to ISA and not with clients or DNS.

Can the ISA server reach to these apps usin URL?
How Did you published these Web Apps in ISA, or you're using a router
between ISA and I.E to publish these Web Apps?
Is the ISA server directly connected to I.E or you have a router?
Is it a 3leg Isa?
Which site IP (not public address, the internal address) are these Apps? and
in Dns what are the ip addresses that map to these Apps?
When you try to ping these Apps which IP returns? and is it right?
These Web Apps needs some especial port to access? Is the Isa Server
blocking that port?

The applications are just ASP pages. They are located on my server INSIDE the
LAN, not out on the internet so i have no need to publish them through ISA.
ISA Server does not limit any access to internal websites, it only controls
traffic in and out of the LAN to the internet. All internal sites are
allowed. I cannot hit the webpage using
http://maxweb.starlitetheatre.local/workorder but I am able to hit it using
http://100.x.x.6/workorder

The ASP pages are all just IE Apps developed in Dreamweaver that run through
port 80 like any webpage.

do you have a Dns domain named starlitetheatre.local ?
Is the maxweb your IIS server and is it registered in starlitetheatre.local
?

when you ping maxweb.starlitetheatre.local which ip returns?
Is the right IpAddress?

Yes my domain is named starlitetheatre.local
when i ping maxweb.starlitetheatre.local (the name of the webserver) it
returns the correct IP address 100.x.x.6. Yes the IIS web server is
registered in the local domain, in fact it is located on the domain
controller. It is also registered in DNS under the correct IP address.

What is the host header and port defined in IIS?
What IPAdress is the Site responding? (All Ip Addresses, a especific
IPAddress?)
