各位大侠好，最近在做关于msf的实验时，是关于meterpreter的，当我设置完RHOST等的时候，输入exploit，就会报错：
msf exploit(ms08_067_netapi) > exploit
[*] Started bind handler
[*] Automatically detecting the target...
[*] Fingerprint: Windows XP - Service Pack 2+ - lang:Chinese - Traditional
[-] Could not determine the exact service pack
[*] Auto-targeting failed, use 'show targets' to manually select one
请问这个问题要怎么解决？目标机器（XP）跟实验机器（Kali 3.14）都是虚拟机里同一局域网的
