Yeap. Its part of the energysaver program on my gigabyte MB, too. When not active, use 0.01 % cpu most of the time and if removed it goes vanish from the list.

ESSVR.EXE is a very legal s/w and came with the M/B package. But always it is connecting to this IP Address (as seen in cmd : netstat -b) -: TCP PHENOM:3304 CLOSE_WAIT 1860 [ESSVR.EXE] TCP PHENOM:3305 CLOSE_WAIT 1860 [ESSVR.EXE] C:\Documents and Settings\Administrator ping Pinging [] with 32 bytes of data: Reply from bytes=32 time=255ms TTL=55 Reply from bytes=32 time=254ms TTL=55 Reply from bytes=32 time=1741ms TTL=55 Reply from bytes=32 time=252ms TTL=55 My qstn is, why a M/B Monitoring program wants to connect to a German server while all it has to do is optimize home computer only? If I close the above TCP connections, it reopens them.
