TMG 2010 - Intra-array comms lots of RPC SYNs

Hi Experts,

TMG set up in an array.
2 TMG servers, 1 configuration storage server.

When having a look at the logs, i've noticed there are thousands of RPC connections being made and

Failed Connection Attempt
Log type: Firewall service
Status: A socket operation was attempted to an unreachable network.  
Rule: [System] Allow intra-array communication
Source: Local Host (
Destination: InterArrayComs (
Protocol: RPC (all interfaces)

This is happening continually.

Any ideas what I can to fix this?

Both servers are up and both are pingable from eachother using the interface for intra-connectivity.

Right-click the rule you have in place and select the configure RPC then deslect the strict RPC option.
