Click on the address object for the UID Agent's IP address. Verify SOURCE/NAME is set to 'Deny msrpc to untrusted'. Verify SOURCE/ZONE is set to 'INSIDE'. Verify SOURCE/Address is set to the Address object for the UID Agent. Verify DESTINATION/ZONE is set to 'GUEST' and 'OUTSIDE'. Verify DESTINATION/Address is set to 'any'.
