controller cannot see minimServer

[psme]

Sorry! Will PM you the full netstat output when the problem happen again.

My setup:
- PC Win7 64bit SP1
- standard onboard LAN Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)
- LAN port in 1G mode, jumbo frame disabled
- I think the network is always on
- no hibernate/standby on the PC, no restart on the NIC

For the 64/32bit problem, I rebooted the PC but minimServer still complain 64/32bit problem. I reinstalled minimServer with same problem. So I reinstall java 64bit (java installer said the version is already installed so I select re-install), then 64bit minimServer runs.

Does that mean I shouldn't have both 32 and 64bit JRE on the PC?
