However, once hotfix 6 was applied (and it did not go well the first, time you must ensure you are in the Exchange Administrators group, domain admins isn&#8217;t enough, it can&#8217;t see the CAS role and breaks OWA), it seemed Exchange was somewhat &#8216;reversed&#8217; or broken. <\/p>\n<p>\u00a0<\/p>\n<p>The issue is, it was resulting in the server sometimes becoming totally unresponsive (to RDP, very slow OWA refresh, etc.) and Outlook Anywhere users seeing a constant &#8220;send\/receive&#8221; that would never finish. The only way to overcome this was to reboot the server, and it was starting to approach a twice a day activity. <\/p>\n<p>\u00a0<\/p>\n<p><span style=\"font-size:14pt\"><strong>The fix: <\/strong><\/span><\/p>\n<p>Here&#8217;s what we discovered and the references. The problem is, Exchange configured to provide Outlook Anywhere on the same machine as the mailbox server (and let&#8217;s face it, sometimes budget comes before implementing lots of servers to divide roles\u2026) needs help with knowing where\/what LocalHost is. And on a Window Server 2008 box where IPv6 (really, why? Is it time to care yet really?) is, Localhost becomes even more difficult for Exchange to find. <\/p>\n<p>\u00a0<\/p>\n<p><em>The fix, in the end was simple: <\/em><\/p>\n<ul>\n<li>Disable IPv6 in your Network Stack <\/li>\n<li>\n<div>Modify your local hosts file with the following: <\/div>\n<ul>\n<li>Remark out the ::1 localhost entry in hosts (use a #) <\/li>\n<li>Add entries for your local server name (hostname and FQDN) and any other SAN names you&#8217;ll have there for your UCC cert <\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>Hope this helps someone.
