I understand that the computer failed to scan for updates after installing Service Pack 2. NOTE: This occurred after an inplace update was done to XP Home-that is, the R was pressed on the 2nd time through. The error code 80072efd was received. This issue can occur if any of the following conditions are true: 1. Some third party background programs, such as anti-virus programs or firewall block access to the Windows Update website. 2. The proxy settings are incorrect. 3. The Host file is corrupted. 4. There is a problem with the server of the Internet Service Provider (ISP) that blocks access to the Windows Update website. 5. The driver for the network card is not working properly. 6. The network card is damaged, impacting the Internet connectivity. At this point, let's try the following steps to troubleshoot the issue. Suggestion 1: Disable firewalls or other Internet browser programs that can affect the Internet connection ===================================== The following programs can affect the connection to the Windows Update site and I suggest we remove or disable them: Download Accelerator GetRight Browser Blaster BitTorrent eMule Sygate Personal Firewall Norton Internet Security Freedom Firewall Zone Alarm Firewall If you have any other similar programs such as a pop-up blocker, please also temporarily remove or disable it to test the issue. Please understand that we are disabling these programs only for the purpose of troubleshooting and we can re-enable these programs after we finish. Note: Please understand that Windows Firewall is on by default and is used to protect the system when the third party security programs were turned off or removed. For detailed information, we can refer to this Microsoft Knowledge Base article: You receive an ""Error 0x80072EE2"" or ""Error 0x80072EFD"" error message when you try to use Windows Update http://support.microsoft.com/?kbid=836941 If this issue appears to be related to a firewall program, I also recommended that you contact the firewall manufacturer to obtain the information to configure the firewall options to allow the access to the Windows Update site. If the issue persists after we disable the third party firewall program, we can check the following. Suggestion 2: Rename the Hosts file ===================== The Hosts file is used for host name resolution. If this file has been modified, we cannot access the Windows Update site properly and can receive the error code. 1. Click Start, Run, type "%SystemRoot%\system32\drivers\etc" (Without the quotation) and then press Enter. 2. Right-click on the file "Hosts" (without quotations) and choose Rename 3. Rename the file to "hostsold" (without quotations) 4. Then, clear the DNS (Domain Name Resolution) cache: 1). Click Start, Run, type "cmd" (Without the quotation) and press Enter. 2). In the opened window, type: "ipconfig /flushdns" (Without quotations)-press Enter. Note: The Hosts file will be generated automatically after being removed. Please try the steps above and let me know the results. If the issue persists, to provide more effective support, please assist me in collecting the following information. How to collect System Information: =========================== 1. Click "Start", go to "Run", type in "MSINFO32" (without quotation marks) and press Enter to start System Information. 2. On the popup window, on the menu bar, click "File", and click "Save"; save it as an NFO file, such as "system.nfo" to your local Desktop. 3. Find the file, right-click on this file, click "Send To", and click "Compressed (zipped) Folder". 4. Please send it as an attachment to v-30nily@mssupport.microsoft.com. How to collect the Windows Update log file: ================================ Note: There are two Windows Update log files with similar names, we will be using the "WindowsUpdate.log" file without a space in the middle of the name. 1. Click on Start, Run and type "WindowsUpdate.log" (without the quotes) 2. Click on the OK button. We will see a file named "WindowsUpdate.log" 3. Now click on the "File" menu and then click on the "Save As" and select "Desktop" in the "Save in" option on the top of the window. 4. Click on the Save button. The file will be saved to your Desktop. Please send the file as an attachment in an email to v-30nily@mssupport.microsoft.com However, if the file is unable to be collected by the above steps, we can also use the following method to collect it. 1. Click "Start", "Run", type: %windir% and then press Enter. 2. In the open window, we will see a file named "WindowsUpdate.log" 3. Please send it as an attachment to: v-30nily@mssupport.microsoft.com Please also let me know if this is a home computer or a work computer. If it is a home computer, does it connect to the Internet directly or through a network device? If it is a work computer, is the computer in a domain? Thanks for your efforts and time. If anything is unclear, please feel free to let me know. I am glad to be of assistance. I look forward to hearing from you. Best Regards, v-30nily@mssupport.microsoft.com
