Important Note(s) about This Release

• Note: As a best practice, Citrix recommends that you install this and other hotfixes only if you are affected by the specific issues they resolve. Otherwise, Citrix recommends that you wait for the next hotfix rollup pack for your product release. Hotfix rollup packs consolidate most previously released hotfixes and allow you to update systems in a convenient, single installation.
• Caution! Installing this hotfix can inadvertently remove the Citrix Licensing component, if present, from the system. To prevent this issue, make sure to install Hotfix XA600W2K8R2X64060, available as Knowledge Center article CTX129224, before installing this and any subsequent hotfixes on systems running Citrix XenApp 6 for Windows Server 2008 R2. [#245185]
• Important: Installing this hotfix over an ICA session is not supported but you can install it through a remote desktop session using an administrator account.
• Installing this hotfix causes the ICA Session performance monitor counter to be removed. As a result, HDX Monitor for XenApp and some EdgeSight user session monitoring cannot find and report on that counter. To prevent this issue, make sure to install Hotfix XA600W2K8R2X64023 or its replacement before installing this and any subsequent hotfixes on systems running Citrix XenApp 6 for Windows Server 2008 R2. [#248473]
• Caution! This release may require you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

New Fixes in This Release

1. After running dsmaint recreatelhc to recreate the local host cache, the IMA service might fail to start and the registry keyHKEY_LOCAL_MACHINE \SOFTWARE\Wow6432Node\Citrix\IMA\Runtime\CurrentlyLoadingPlugin displays "AdMgmtSs.dll".

   To enable this fix, you must set the following registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\IMA\Runtime
   Name: AlwaysReadGpoFromDB
   Type: REG_DWORD
   Data: 1

   [From XA600W2K8R2X64111][#LA0633]

Fixes from Replaced Hotfixes

1. Restarting the IMA Service while the data store is unavailable results in the temporary deletion of certain farm policy settings from the server. This occurs because reading the settings from the local host cache - intended as a backup mechanism for retrieving farm policy settings in case the data store is down - does not work properly. Even without this fix, the issue is temporary: restarting the IMA Service as soon as the data store is available again repopulates the farm policy settings. This fix addresses the issue that prevents the proper reading of the farm policy settings from the local host cache in the first place.

   [From XA600W2K8R2X64009][#234694]

2. Configuration logging fails for administrators whose SQL Server password starts with a capital letter S.

   [From XA600W2K8R2X64049][#207951]

3. New XenApp policies and changes to existing XenApp policies are not saved if policies are being created or modified from multiple consoles by different administrators at the same time.

   With this fix, the latter console produces an error message when trying to save new or modified policies. To enable this fix in its entirety, you must also install a Delivery Services Console or a Group Policy Management Console hotfix that contains Fix #256226.
