ISSUE

Basic steps to follow to ensure you have done everything possible to setup communication between the Unitrends appliance and the Unitrends Client Agent for Windows.

RESOLUTION

1) Update the Unitrends appliance to the current release.

2) If you are protecting uses security software (antivirus, antimilaware, firewall, etc.), do the following first:
 • Exclude the following directories from scans:
        C:\PCBP; C:\unicbt; C:\Unitrendsvcbt
 • Allow at the minimum, the following to exist and operate as needed:
       ♦ In the C:\PCBP directory: WBPS.exe, WBPR.exe, bpnetd.exe
       ♦ In the C:\windows directory: winexesvc.exe
 • Follow instructions in KB 5800 and 5520 for additional advice.

• Create inbound and outbound firewall rules that allow TCP ports 1743 thru 1749 at allowed to communicate between the Unitrends Appliance's IP and the computer you are protecting.

3) Install the Unitrends Client Agent (you might need to temporarily disable the security software). You do not need to wait to update the Unitrends appliance as you can download the agent from:

4) Log onto the Unitrends appliance and go to the CONFIGURE > Protected Assets Tab. Find the computer that had the issue (in your case, HRM_Base) and click the box to the left of the name. Click Edit, and then click Save.
   • If you get an error, ping the IP Address listed from the Unitrends SSH command line. Correct as needed.
   • Test communications by running the telnet command followed by the computers hostname or IP address, and then the number 1743. Assuming the IP is 192.168.1.11 you would execute: telnet 192.168.1.11 1743
     The output should show it connected on port 1745. If it does not, follow the steps in KB 1406:

5) For any affected computers, please run a new 1-Time (on-demand) full backup.
