New Solarwinds server trying to communicate with old Solarwinds server

I have a new solarwinds server that was commissioned several months ago, the old server has been decommissioned and removed but I am getting hits across my firewall from the new server to the old trying to use port 17777 and ports 8080.  I am not the system administrator for the server and I have brought it to his attention but he doesn't know why it is doing this.  Can anybody help me out with this problem?
