Hi, Thank you for posting. Since everything worked before, a quick solution is to restore the system back to the previous status when the issue didnt occur with System Restore. (Note: Performing a system restore may cause the loss of the current system settings; therefore, before doing this, please make sure that the system restore point is not too old and set a restore point for the current status.) If the issue persists, please also try the following: 1. Temporarily disable or remove your security software on both computers (Anti-virus software, firewall, etc.) to see if this problem is gone. 2. Please perform a Clean Boot on both computers to check the issue. Clean boot ================= 1) Click the Start Button type "msconfig" (without quotation marks) in the Search box, and then press Enter. Note: If prompted, please click Continue on the User Account Control (UAC) window. 2) Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray). 3) Click the "Startup" tab, click "Disable All" and click "OK". Then, restart the computer. When the "System Configuration Utility" window appears, please check the "Don't show this message or launch the System Configuration Utility when Windows starts" box and click OK. NOTE: we can go back to normal boot by running msconfig again and checking on Normal Startup in the General tab. In the Clean Boot Environment, the third party services and applications are disabled, please check if the issue reoccurs at this time. If the problem does not occur, it indicates that the problem is related to one application or service we have disabled. You may use the MSCONFIG tool again to re-enable the disabled item one by one to find out the culprit. Hope this helps. Thanks.Nicholas Li - MSFT
