Cookieless browsing broken after update KB4580979
Upon running Windows Update KB4580979, .Net 4.7.2 projects that have the SessionStateSection.Cookiless Property set to AutoDetect no longer functions as expected. Previously, a browser that blocked cookies would be redirected to the same page with the querystring /default.aspx?AspxAutoDetectCookieSupport=1 and upon the system detecting that cookies were not supported it would redirect again to a cookiless session URL e.g. /(X(1)S(adl04pietheradyfawfaqlym))/default.aspx?AspxAutoDetectCookieSupport=1 Since the update, a browser would continously be redirected to /default.aspx?AspxAutoDetectCookieSupport=1 until the redirects exceeded the maximum redirects. Relevant Web.config section: <configuration> <system.web> <sessionState cookieless="AutoDetect" /> </system.web> </configuration> Windows Server 2019 DataCenter Version 1809 OS Build 17763.1369
SSL certificate private key missing, on recovery process smart card pop up appear
I can add an SSL certificate to IIS server certificates, but when we try to binding SSL certificate to our app it's not listing there, then checked IIS server certificates again, the added certificate not found there, finally realized that issue was due to missing of the private key, then I tried to recover that by executing following command certutil -repairstore my <Serial_number> but getting smart card pop up, then updated group policy of smart card (disabled smart card), after that checked again, pop up still shows Windows Server 2019 data center 64 bit Refer: https://www.namecheap.com/support/knowledgebase/article.aspx/9773/2238/ssl-disappears-from-the-certificate-list-on-windows-server
