Dataprotector: System error: HOST_NOT_FOUND

I have been working a bit with migrating a Data Protector cell manager, when moving a client i recieved the following error:

[Critical] From: BDA-NET@ " [/boot]"  Time: 02.09.2011 09:08:03
Cannot connect to Media Agent on system , port 49708 (IPC Invalid Hostname or IP Address
System error: HOST_NOT_FOUND) =>

The cause for this was that the client could not look up the cell manager. I solved this by simply adding the cell manager in the hosts file of the client. You can verify this problem by simply doing a ping or nslookup against the cell manager, from the client itself.
