I have just upgraded my BES from 4.0 to 4.1 and have also installed MDS. I can activate the MDS on the devices but when I try to run applications such as the simple convertor application supplied by RIM it allows me to enter the data and submit it but after a about a minute I get the following error in my log files.

{H T T P://xml.apache.org/axis/}hostname:bes (I had to put spaces in between http because I was not allowed to put URLs' yet)

java.net.ConnectException: Connection timed out: connect

I also get the following error on my handheld
An error has occurred, SOA connection failed; nested exception is:
java.net.connectException: Connection timed out: Connect.

I am fairly new to all this stuff and vodafone done the install so I am still learning myself but if anyone has any pointers then please let me know. I have checked the Java versions and .NET framework etc and they are all at the correct levels recommended levels.
