Using powercfg -requests I get:[DRIVER] Filesystem\srvnetAn active remote client has recently sent requests to this machineThis blocks sleep mode (a "feature" of sleep mode).I have tried disabling wake for sleep on adaptors. Disabling home group. disabling media center, unistalling windows media, disable auto update, no media sharing....Because there is a long timeout of maybe15 minutes or longer on this it so it is hard to diagnose if it is coming from the local machine or the other Win 7 on the network. The problem seemed to start when I upgrade the second machine from Vista though not 100% sure.Seems like each machine keeps the other awake? I have also suspected the Dlink router and turned all of its "added value" features off. Where is this "remote client" and how to diagnose?Is there a setting to at least turn the time out to a minute or less?One machine runnning Win 7 7600 64 before and after this problem started. The other was Vista and now Win 7 7600 32 since the problem began in BOTH machines.

Hi Girvan, Mostly this issue is caused by network adapter driver. Could you please download and install the latest network adapter driver to test the isue?In addtion, if you disable network adapter on the computer, does Sleep work normal?Thanks.

I have this same problem. The Windows 7 desktop computer never sleeps. It never even blanks its display. POWERCFG.EXE -REQUESTS returns: -------- C:\Windows\system32>powercfg -requests DISPLAY: None. SYSTEM: [DRIVER] \FileSystem\srvnet An active remote client has recently sent requests to this machine. AWAYMODE: None. --------- C:\WINDOWS\system32\fsmgmt.msc shows no open sessions and no open files. I have the latest available drivers for the Gigabit Ethernet network (Realtek 7.6.820.2009)

I have got the same exact problem. How can I find out who this remote client is? May be this is just a bug.... The same problem even if network controller is disabled. Or even when the mouse and keyboard are disconnected. The powercfg -lastwake shows wakecount 1 but does not identify who woke it up. If it is woken up by mouse or keyboard it does identify it as a USB hub device or something. This is on a newly built computer, used a hard disk that had Vista 32-bit and upgraded to Windows 7 64-bit. The Windows partition was formatted so it is a clean install. Even if I manually put it to sleep, it will even wake up from sleep, though luckily does not turn on the monitor in my case. Just the power lights and fans go full speed for a few minutes, and then back to sleep. I have seen this happen as frequently as 15 minutes. As an alternative I can hibernate the machine, but then mouse/kbd will not wake it up and I have to reach for the power button everytime.

I still have this problem. It is inconsistent, though. Sometimes the system will sleep normally for a while, and then go back to staying active 24/7. It appears that once the system has seen any connection from another device, it will never sleep again. Even after a reboot, even days after the occurrence of "An active remote client has recently sent requests to this machine" it will refuse to go into sleep mode. Since my last post, a new driver for the Realtek Gigabit Ethernet has become available - 7.18.322.2010. It does not seem to help the problem. I have checked the power settings using "POWERCFG -QUERY". The "Sleep After" setting has not changed from my setting value of 15 minutes. Sometimes I to go into the Power settings control panel and re-apply the sleep settings, then manually put the system into sleep mode. The system will wake and sleep normally again for a while, until it thinks there is another "active remote client". I have a script that runs as an hourly scheduled task. It writes the output of POWERCFG -REQUESTS into a log file. I have examined this log, and I can see days where the computer runs all day while logging "DISPLAY: None. SYSTEM: None. AWAYMODE: None." each hour. If there are no requests to not sleep, and the settings are to sleep after 15 minutes, why would it not sleep? This looks like a bug in Windows 7 to me.
