Hi Andy,
 
When the IP address changes, stopping and restarting the server should
fix the problem.  During startup, the server grabs the current IP
address.

So, once the IP address changes and there is failure once, is a
reinstall necessary?  Once I got back to the office, I'm fairly sure I
had the same dynamic IP I had before I left - should it have worked?  On
development machines that use dynamic IP addresses, how can we be sure
that this does not happen?
 
Thanks.
 

Andy

Hi Andy,
 
The MapGuide Server gives out it's IP address to the Web Extensions and
MapAgent when a Service is requested.  The Server interrogates the IP
address for the machine when the mgserver process is started.  If the IP
address of the machine changes while the mgserver process is running
then you will see the behaviour you have mentioned below.  The IP
address is only given out to Service level operations.  The MapGuide
Admin does not use the same functionality.
 
Hope this helps,

Trevor

Hi, 
I installed MapGuide Enterprise with the .NET web extensions about two
weeks ago on my development machine and got everything re-configured,
including WMS with the newly required Bounds parameter.  Well, after
being on vacation and trying to do some stuff with it today, it was
mysteriously broken.  Everything I did that would access the web
extensions would fail with:

Cannot establish connection. Exception occurred in method
MgServerConnection.Open at line 94 in file
c:\build_tux_area\mgdev\common\service\services\ServerConnection.cpp 

Everything worked OK in MapGuide Admin (PHP based), when running all of
the mapagent tests, and when making WMS calls.  Studio would enumerate
and display all resource information.  But everything related to
rendering a map or a web layout would fail.  I tried to run a repair on
the web extensions and that did not help.  I had to uninstall and
reinstall the web extensions in order for the problem to disappear.  

We've seen this before with MapGuide Open, and it appears to still be a
problem.  I did not install, uninstall, or re-configure anything on this
machine during this time period.  The only thing I did was disconnect it
from it's home network and connect to the internet through a hotel
internet connection to check email.  Very strange, indeed.
