rsync not running

[Jason King]

My rsync server is not syncing with one of my client servers. When I run 
the following command:

rsync -av projects.informs.com:var/lib/mysql /home/portalsbackup/informs/

I get the following error message:

projects.informs.com: Connection refused
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)

I dont' understand because I can ps -aux | grep rsync and I can see the 
rsync daemon running. Anyone have any ideas?
