Re: Compiled Web App Unavailable to Some Users

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi Juan,

I think you're right...the external IP cannot be seen by the local machine
or anyone within that network, but using the internal IP, its
fine...phew!...I think this explains it, although I don't completely
understand.

So, I just have one last question: do you think (given the information) it
should be okay...I don't know of anyone else who is having trouble accessing
the app...just the users within the network.

Thanks Juan!

if telnet can not connect you have a network problem (either router or proxy)

Hi, Bruce.

The problem might be as simple as the network using NAT addressing.
In that case, the external IP can't be seen by the local machine.

I.O.W., if his box has a local network address (10.0.0.x, for example)
there's no way his box can see the external IP assigned via NAT.

That's why I suggested using either localhost,
or mapping 127.0.0.1 to the domain name in the hosts file.

The machine's name would work, too, for development purposes.

you should use a network sniffer to check if you can connect. if you don't have one, first use
telnet specifying to connect on port 80. if telnet can not connect you have a network problem
(either router or proxy). if you can connect type:

GET /default.aspx HTTP/1.1

the server shoudl respond.

Hello Everyone:

I am having the most bizarre problem with my asp.net web app...this is my first web app in
asp.net and I inherited it from a programmer who quit...so, I am not completely familiar with all
the ins and outs.

The problem is that some machines can open my web app and some machines cannot...In fact, the
server, which is hosting the app and has VS.Net installed, cannot access the app via the external
IP address, but other machines can...weird, huh?

I tried pinging the IP from the server and that worked...telnet failed.

I've tried removing the Windows Security and that didn't help.

I tried including the port number in the IP Address in my browser and that failed.

I checked IIS and it is running (which, I guess is obvious b/c some users are able to see the
app).

I verified that the port 80 is open (which, again, is obvious).

I messed with different browsers (Firefox and Netscape) and still can't log in.

The error message I'm getting is "this page cannot be displayed"...I tried turning off Friendly
HTTP error messages and still get the ambiguous message.

Not sure where to start on this...I've put in about 20 hours (which is to be expected,
considering I'm new)...but, I'm close to my wits end.

Is there a way to trap the error?...Has anyone ran into this before?...Anyone have an idea?

Thanks!!!
