Windows Firewall issue, Inbound rule opend all, still not the same as turning off

Question

This is Windows Firewall issue on Windows 8.1 Pro. 
Backup Exec server cannot expand a computer node in selection list. I drill down to Microsoft Windows Network/Domain/Computers, then when I tried to expand a Windows 8.1 Pro computer node, it hangs out. 
I narrowed this problem to Windows firewall related issue on Windows 8.1 Pro computer. 
When I turn off Windows Firewall on Domain profile, Backup Exec Selection expands the computer node of the Windows 8.1 Pro computer. So, I created an inbound rule opening all to BAckup Exec server as following, but it's still not the same as turning off
Windows firewall specifically on Windows 8.1 Pro computer;
Any Local IP address, Any Remote IP address, Any port, Any protocol, All Interface, All Programs and Services, All profiles(Domain, Private, Public)
And there are no rules blocking any which may override the above rule. 
Ethernet on Windows 8.1 Pro computer shows profile is linked with Domain, but just to make it work, I selected all profiles.
Even though I opened all available in inbound rule, it's still not the same as turning off windows firewall. Why am I missing? 

Answer 1

It looks as something related to RPC(UDP 135), but even when inbound rule is all open, why it matters? RPC seems working fine only when firewall is turned off on domain profile. 
Protocol 17 is UDP
Port: 135
