The Symantec Endpoint Protection Manager web console is not accessible after installing Windows Security Update 956572 (MS09-012). After the trust certificate step, Internet Explorer remains on the localhost:9090 page.

 There is no visible error message in Internet Explorer. Other browsers might display "Error 310 (net:: ERR_TOO_MANY_REDIRECTS)".


The issue is caused by changes that were made to the base address of Advapi.dll after installing Microsoft Windows 2003 Server Security Update MS09-012.



Microsoft has released an update to the security patch, which has been reported to solve the problem. For information on this update, go to http://support.microsoft.com/default.aspx?scid=kb;EN-US;971812.
