Hi Jim Yes, I have rebooted the servers. Particular web sites no longer load after installing the patch. Uninstalling the patch doesn't fix the issue either. The Citrix servers that were not patched all work fine so the patch definitely changed something to break this Regs Ang Date: Tue, 28 Oct 2008 08:31:20 -0400From: jkenzig@xxxxxxxxxxx: thin@xxxxxxxxxxxxxxxxxxxx: [THIN] Re: kb958644 broke IE 6 browsingDid you reboot after the patch? It is required. Jim Kenzig Blog: http://www.techblink.com On Tue, Oct 28, 2008 at 6:17 AM, Angela Smith <angela_smith9@xxxxxxxxxxx> wrote: HiIs anyone else having issues with hotfix kb958644? I have installed the patch on 90% of our Windows 2003 CPS 4 Servers and I now have issues getting to specifc Web Sites. The non MS patched Citrix servers can browse these sites without any issues. I now get the following error on certain web sites:The Page cannot be displayedThe page you are looking for is currently unavailable. The web site might be experiencing technical difficulties, or you may need to adjust your brwoser settingsCannot find server or DNS ErrorI have installed the Patch on Windows XP running IE 7 and I can browse to the troublesome web site. It refuses to work on my Citrix farm with the MS patch. The Servers are running Windows 2003 SP2 with CPS 4.0 running IE6.Has anyone had similar issues??Thanks _________________________________________________________________
