Web App can't find web service

[WhiskyRomeo]

When my web service and web application are on the same server (Windows 2003
Standare), everything work fine. When the web application is on a different
server (Windows 2003 Web Server), the application fails giving the error
message I have posted below the code. Any help is appreciated.

Again the web service is working with the web application on the same box.
Additionally, the web service is working across the LAN because a Windows
..Net application is accessing it from the LAN client machines.

Are you talking about something like . . .
Dim myCred As New
NetworkCredential(SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain )

wsCommon.Credentials = myCred

This may be basic to you but to me the credentials is a mystery to me since
if you had wanted to have a public webservice -- would you provide the
credentials to access it?

I always could see the web service via IE directly and yes it did present me
with a Windows login. For example wsCommon.asmx displays listing all its
methods.

I created credentials based on the same username, password, and domain as I
used in replying to the Windows login but I still get the same result.

Last night, your responses kept me working on it. I have this web service
on another server available to me over the internet. So I pointed my urls to
it and ran the project on my local development machine (don't know why I
didn't think of this before). It works perfectly. It was hitting a web
service over 1500 miles away. I was even surprised by the performance
because a prettly large dataset is returned.

So I installed this version of the project on the server where I am having
the problem and I still get the 404 error. It returns so fast, that there is
no way it went out across the internet and hit the web service. At this
point, I am suspecting a server/LAN configuration and have the LAN admins
looking at this now.

I appreciate the offer for help and may yet have to take advantage of it.
But, I am pretty sure everything with the web service itself is ok.
