这真是奇怪 – 我有一个解决方法（阅读），但我很想知道为什么它的作品。
我有一个VPN设置工作正常与WinServer2003服务器和Vista客户端。
然后我设置一个新的Win7框来访问相同的服务器。 服务器正在运行WINS。
这两个客户端都可以进入VPN，并通过IP4地址在服务器端Ping机器。
但只有Vista客户端可以通过NETBIOS地址（机器名称）ping机器。 Win7客户端刚刚返回“找不到主机”。
据我所知，客户端configuration相同。
偶然的时候，我发现，如果我在Win7客户端上运行一个tracert（追踪到服务器端的任何一台机器的路由），那么在NETBIOS工作之后。
例如（这是从Win7的cygwin命令行框，编辑密码等）：
$ rasdial "vpnName" Dave passWord Connecting to vpnName. Verifying username and password... Registering your computer on the network... Successfully connected to vpnName. Command completed successfully. Dave@QUIET ~ $ ping henshaw Ping request could not find host henshaw. Please check the name and try again. Dave@QUIET ~ $ tracert 10.1.10.1 Tracing route to www [10.1.10.1] over a maximum of 30 hops: 1 39 ms 47 ms 49 ms ASH [10.1.10.184] 2 44 ms 31 ms 32 ms www [10.1.10.1] Trace complete. $ ping henshaw Pinging henshaw [10.1.10.92] with 32 bytes of data: Reply from 10.1.10.92: bytes=32 time=36ms TTL=127 Reply from 10.1.10.92: bytes=32 time=46ms TTL=127 Reply from 10.1.10.92: bytes=32 time=35ms TTL=127 Reply from 10.1.10.92: bytes=32 time=41ms TTL=127 Ping statistics for 10.1.10.92: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 35ms, Maximum = 46ms, Average = 39ms （ASH是Server2003服务器盒，10.1.10.1是网关。）
到底是怎么回事？ 为什么Win7盒子首先采取不同的行动，为什么tracert会修复它？

根据@Sane的build议，这里是两个客户端的ipconfig all输出：
