It might leak memory on domain controllers (DCs). This issue occurs after you install KB5035857 (March 12, 2024). The leak occurs when on-premises and cloud-based Active Directory DCs process Kerberos authentication requests. This substantial leak might cause excessive memory usage. Because of this, LSASS might stop responding, and the DCs will restart when you do not expect it.<\/p>\n<p>\u3053\u306e\u66f4\u65b0\u306b\u3088\u308a\u3001\u30ed\u30fc\u30ab\u30eb\u30bb\u30ad\u30e5\u30ea\u30c6\u30a3\u30aa\u30fc\u30bd\u30ea\u30c6\u30a3\u30b5\u30d6\u30b7\u30b9\u30c6\u30e0\u30b5\u30fc\u30d3\u30b9\uff08LSASS\uff09\u306b\u5f71\u97ff\u3059\u308b\u65e2\u77e5\u306e\u554f\u984c\u304c\u89e3\u6c7a\u3055\u308c\u307e\u3059\u3002\u3053\u306e\u554f\u984c\u306b\u3088\u308a\u3001\u30c9\u30e1\u30a4\u30f3\u30b3\u30f3\u30c8\u30ed\u30fc\u30e9\uff08DC\uff09\u4e0a\u306e\u30e1\u30e2\u30ea\u304c\u30ea\u30fc\u30af\u3059\u308b\u53ef\u80fd\u6027\u304c\u3042\u308a\u307e\u3059\u3002\u3053\u306e\u554f\u984c\u306f\u3001KB5035857\uff082024\u5e743\u670812\u65e5\uff09\u3092\u30a4\u30f3\u30b9\u30c8\u30fc\u30eb\u3059\u308b\u3068\u767a\u751f\u3057\u307e\u3059\u3002\u3053\u306e\u30ea\u30fc\u30af\u306f\u3001\u30aa\u30f3\u30d7\u30ec\u30df\u30b9\u304a\u3088\u3073\u30af\u30e9\u30a6\u30c9\u30d9\u30fc\u30b9\u306eActive Directory DC\u304cKerberos\u8a8d\u8a3c\u8981\u6c42\u3092\u51e6\u7406\u3059\u308b\u3068\u304d\u306b\u767a\u751f\u3057\u307e\u3059\u3002\u3053\u306e\u5b9f\u8cea\u7684\u306a\u30ea\u30fc\u30af\u306b\u3088\u308a\u3001\u30e1\u30e2\u30ea\u304c\u904e\u5270\u306b\u4f7f\u7528\u3055\u308c\u308b\u53ef\u80fd\u6027\u304c\u3042\u308a\u307e\u3059\u3002\u3053\u306e\u305f\u3081\u3001LSASS\u304c\u5fdc\u7b54\u3057\u306a\u304f\u306a\u308a\u3001\u4e88\u671f\u3057\u306a\u3044\u3068\u304d\u306bDC\u304c\u518d\u8d77\u52d5\u3059\u308b\u3053\u3068\u304c\u3042\u308a\u307e\u3059\u3002\n<\/p><\/blockquote>\n<p>\u66f4\u65b0\u30d7\u30ed\u30b0\u30e9\u30e0\u306f\u305d\u308c\u305e\u308c\u3001Microsoft Update Catalog\u3067\u306e\u307f\u63d0\u4f9b\u3055\u308c\u3066\u3044\u308b\u305f\u3081\u3001IT\u7ba1\u7406\u8005\u306f\u624b\u52d5\u3067\u30c0\u30a6\u30f3\u30ed\u30fc\u30c9\u3057\u3001\u30a4\u30f3\u30b9\u30c8\u30fc\u30eb\u3059\u308b\u5fc5\u8981\u304c\u3042\u308a\u307e\u3059\u3002<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Windows Server 2022\u5411\u3051\u306e3\u6708\u306e\u6708\u4f8b\u66f4\u65b0\u30d7\u30ed\u30b0\u30e9\u30e0KB5035857\u3092\u9069\u7528\u3059\u308b\u3068\u3001\u30c9\u30e1\u30a4\u30f3\u30b3\u30f3\u30c8\u30ed\u30fc\u30e9\u30fc(DC)\u3067LSASS(Local Security Authority Subsystem Ser [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":120075,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"swell_btn_cv_data":"","footnotes":""},"categories":[3],"tags":[3298],"class_list":["post-120074","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-windows","tag-windows"],"_links":{"self":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts\/120074","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/comments?post=120074"}],"version-history":[{"count":0,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/posts\/120074\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/media\/120075"}],"wp:attachment":[{"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/media?parent=120074"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/categories?post=120074"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/softantenna.com\/blog\/wp-json\/wp\/v2\/tags?post=120074"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
