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 17763.1369Windows Server 2019 - Upgrade of certain packages fails - Repair fails as well
Situation: - Windows Server 2019 - Long Term Stable release - some upgrades work in Windows Update - specific Updates fail (regardless whether I install via Win Update or download via Microsoft Catalogue) See below (sorry for German UI) As you can see: KB4586082 -- SUCCESS KB4586839 -- FAIL I have tried repair using sfc /scannow --> no problems found dism .... (see below) --> problem found BUT repair via /restoreHealth fails Any ideas how to solve this without data loss and not too long downtime? Today again a rollback:
