Weird: J2SE 1.6.0_01-b06 seems to crash TCP on Win2k

Has anybody heard of a situation in which attempting to open a socket (for a Telnet connection) from J2SE 1.6.0_01-b06 on a Win2k box causes it to lose all connections with the outside world until hard-rebooted?

The exact same jar works fine on a different Win2k box with J2SE 1.6.0-b105.

I just put 1.6.0_01-b06 on the box that had 1.6.0-b105. Everything still seems to work fine.

The Telnet conversation gets stuck in a call to SocketInputStream.read(). When it gets stuck, it sits there for at least a minute or so, and during that time, the mouse pointer alternates repeatedly between freezing for several seconds and responding for several seconds. Finally, a "Connection reset" SocketException is thrown, and by this time, the TCP stack is toast.
