Blackberry Manager - MDS

[geordiedave4]

I have recently set up the Blackberry Infrastructure on my network. I installed the BES and MDS services on seperate machines. I am using version 4.1.2
When I load Blackberry Manager on either the Servers or PC's it works fine except when I click on my MDS server I get an error message saying "There was an error retrieving data".
Looking in the logfile it seems that it is trying to use and incorrect username and password to connect to the MDS Server(its trying to send a blank password).

Does anyone know where I can change the details that Blackberry Manager is using to connect to the remote MDS server?

If I use the website address -

https://mdsserver:7443/mds

then I can connect fine with the correct login details, so I know the MDS services are working fine.

Any help would be appreciated.

Thanks
