Problem:

After opening the deployment wizard, when trying to advance from the introduction page to the job type page we get the error message:

An error occurred connecting to the deployment manager. Click help for more information (dpm225303)

Symptoms:

Check the Domain Manager's  DSM\logs\TRC_CF_DMDEPLOY_0.log file and verify if you see messages like this regarding the remote machine that is getting that message dpm225303.

Sample from log:

NOTE: %SERVERNAME% should be the remote explorer machines host name

 

Solution:

The way to fix this is to ensure that the IP address , short hostname and fully qualified domain names are resolving ok between the Domain manager machine and the remote explorer.

You should check the DNS entries on the Domain Name Server or you can bypass DNS by editing the hosts file located in the Windows\System32\drivers\etc and add the IP address , FQDN and short name.

sample entry 

1.1.1.1          some_host         some_host.ca.com

Relaunch the remote DSM Explorer and go back into the Deployment Wizard and you should then be able to successfully connect to the Deployment Manager.
