xml parsing error

[murrayja]

I have a customer who requires a webservice written in C# and requires IIS as an app-server.
I have two computers on a LAN one of which, 'B', came with XP-PRO the other computer, 'A', I just upgraded from XP-HOME to XP-PRO so I could have IIS in both machines. Both are now running IIS 5.1.

I have the same service installed in virtual directories on both computers 'A'=localhost and 'B'=dogpatch.

From 'A', using Firefox, I try to connect to

http://localhost/Echo/Echo.asmx

and get an error on the .asmx file.

XML Parsing Error: not well-formed
Location:

http://localhost/Echo/Echo.asmx

Line Number 1, Column 2:
<%@ WebService Language="C#" CodeBehind="Echo.asmx.cs" Class="Echo.EchoClass" %>
-^

From 'A', again using Firefox, I connect to 'B'

http://dogpatch/Echo/Echo.asmx

it works as advertised.

I have tried re-loading IIS into 'A' to no avail and the only IIS that I have is on the CD I used to upgrade 'A'.

Any ideas?
