pinoy, It sounds as though your network settings aren't properly configured from within Windows - is your Internet Explorer, for example, working properly? Try going into your Network and Sharing Center, and making sure that nothing is amiss with Proxy settings, DNS, etc., as per your current connection.-Alex

This particular error code indicates that the issue is caused by network connection. There are several possible reasons. 1. Firewall blocks.2. Network adapter driver is not correct.3. Proxy settings are not correct. 4. The proxy you connect to blocks the data of the product activation. Please confirm the root cause and troubleshoot with the above prompt.Arthur Xie - MSFT

yes i am connected to the internet, otherwise i wont be able to post this. i tried to disable all the firewall, still no luck how do i fix proxy settings?

pinoy, To configure your proxy settings, open the Network and Sharing Center from the Control Panel, and select Internet Options from the bottom of the left pane. In the resultant menu, navigate to the Connections tab and click the LAN Settings button from the bottom-right corner. In the LAN settings menu, make sure that only "automatically detect settings" (or nothing at all) is checked.-Alex

Have you tried rerunning the Activation recently?The fact that you're able to post messages to these forums generally contradicts an 0x80072EFD error,unless the issue is exclusive to some event of the activation service itself.The other possibility is that DNS is not properly resolving the target hostname for the Activation service,or a router/firewall is blocking traffic to the destination IP Network,or a defective entry is in the machine's routing table causing the traffic to be routed incorrectly.If you have the ability to capture logfiles from your router/firewall, it might be useful to see what's happening with the traffic that's being sent.You might also just use the telephone and activate over the phone. (Shucks, somebody needs to test Windows7 Phone Activation anyway. <g>)Lawrence Garvin, M.S., MCITP:EA, MCDBA Principal/CTO, Onsite Technology Solutions, Houston, Texas Microsoft MVP - Software Distribution (2005-2009)

I have the Same issue. Will not let me Activate.Im using it right now. Win 7 X64 Ultimate 7100Brand new Box built it yesterday.

Very peculiar.The error code: 0x80072EFD ismost common when using the Windows Updates website as it scans your system.For some strange reason your system's Activation process (pinoy and SPC) appears to be being redirected to the Windows Updates servers instead of the Activation servers.I reckon it's possible that the Windows Update Servicewithin Windows 7 might be interfering with the Activation process. Perhaps some clean up of the Windows Updates temporary directory (C:\Windows\SoftwareDistribution) might be in order. In the C:\Windows\SoftwareDistribution directory there are5 folders that can be emptied out: AuthCabs, DataStore, Logs (subfolder of DataStore), Download, and EventCache.To do the clean up properly and safely Windows 7 will need to be in Safe Mode. Pressing the F8 key after the BIOS POST and before (and during)Windows 7 begins to boot up should work to get Windows 7 into Safe Mode. If that doesn't work: RUN>msconfig, Boot tab> check the box below for SAFEBOOT, APPLY, OKthen you'll be prompted to restart.Whilst in Safe Mode navigate to the C:\Windows\SoftwareDistribution directory:* In the AuthCabs folder - delete everything in there.* In the DataStore folder - delete the DataStore.edb file.* In the Logs folder (within the DataStore folder) - delete everything in there. Do not delete the Logs folder itself.* In the Download folder - delete everything in there.* In the EventCache folder - delete everything in there.And that's if for the clean up.Go back to RUN>msconfig, Boot tab and uncheck the box for SAFEBOOT, APPLY, OK and restart.When you get back into Regular Mode of Windows 7 run Windows Updates. Don't be alarmed about not having any Windows Updates history. Windows Updates will scan your system and will detect all the successful Windows Updates and list them in a different Window (Installed Updates if I remember correctly). You will have to "re-hide" any updates that you had hidden previously before you did the clean up of the SoftwareDistribution directory.If you continue to get that same error...geeze...the only other thing I can think of is to stop the Windows Update Service (in the Adminstrative Tools>Services) before running the Activation process again.GA P35 DQ6 Mb, Intel Wolfdale 8600 3.33Ghz C2D CPU., 4x2Gb Mushkin DDR2 1066 PC2 8500 Ascents Memory Mods., PNY-nVidia GE Force 8800 GTS (640MB), 4-Western Digital Caviar SATA(2) HDD's (internal), 1 EIDE-USB External; Hauppauge PVR 1600 TV tuner, Dual Monitor: (1) Standard up top, (1) WideScreen below; Altec Lansing Speakers.

Can a different program interfere with the activation?

All programs that alter the network connection settings can interfere. Some download managers or download accelerators do that, for instance. Filesharing/torrent programs can change MTU settings for better transfer rates, another possibility.Mobile AMD64 3000+, VIA Apollo K8T800 chipset, 1 G RAM, ATIRadeonMobility 9700, 20x DVDRW, C:XPSP3 (55G),D:WIN7 (25G),F:DATA (250G)

It is VERY possible that NOD32 is disrupting (not necessarily blocking)your connection to the Activation server.I use ESET Smart Security. I know the onlyreal major difference between NOD32 and Smart Security is the Personal Firewall and the AntiSpam modules. I am not sure if NOD32 provides any type ofscanning or filteringfor websites. You would have to go into the Advanced settings and check to see if there is anything for website access protection. Sometimes the svchost.exe gets checked for browser filtering so it should be unchecked. Also, if your NOD32 has a website access/Active scanning section, look in there to see if any other Windows processes are checked for scanning. If there are any essential Windows processes being filtered at all that could definately create some havoc with the Activation process.GA P35 DQ6 Mb, Intel Wolfdale 8600 3.33Ghz C2D CPU., 4x2Gb Mushkin DDR2 1066 PC2 8500 Ascents Memory Mods., PNY-nVidia GE Force 8800 GTS (640MB), 4-Western Digital Caviar SATA(2) HDD's (internal), 1 EIDE-USB External; Hauppauge PVR 1600 TV tuner, Dual Monitor: (1) Standard up top, (1) WideScreen below; Altec Lansing Speakers.

I like the person who posted this am having the same issue, kinda. I installed activated my copy of Win7RC 7100 build 4-5 dyas ago.. I booted my system up this morning and now it's saying " This copy of windows is not genuine" I've tried to re-enter the code i got and i get the above error. I've tried everything and still nothing.. Again I had my copy activated and now nothing.

You may launch "slui.exe 4" from Start Search box, then follow the instruction to Activate the system via phone.Arthur Xie - MSFT

Hello,This may be going backward a bit but all of you having trouble activating, is the time both in Windows and BIOS accurate? If these times are way off you will not be able to activate.-Scott
