Theres two ways of solving this.
Method 1 is to make an access rule in the Network Monitor to allow all IP traffic (In/Out) from 169.254.2.0 255.255.255.252 to 169.254.2.0 255.255.255.252. This will allow all forms of communications between the IP address 169.254.2.1 and 169.254.2.2. These two are respectively your PC ( .2) and your PPC ( .1).
Method #2 is to allow inbound TCP connections from your PPC on IP address 169.254.2.1 on the following ports:
ICMP Any
TCP 990
TCP 999
TCP 1025 (for Outlook communication)
TCP 1069
TCP 5678
TCP 26675
TCP 36914 (for Outlook communication)
These ports can be verified in the logs. Just check for blocked entries from the IP address mentioned above
