Important Notes 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.
• 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.
• 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.

Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, see Citrix eDocs, the Citrix Product Documentation Library.

New Fixes in This Release

1. In smart card environments, servers might experience a fatal exception with stop code 0a on cdm.sys or CtxAltStr.sys.

   [From XAE500R01W2K8X64095][#198109]

2. If a smart card does not return any response from the client side, all logon requests to the same XenApp server are delayed in the meantime. The issue occurs because the smart card writing time-out and retry count are hard-coded.

   To reduce the wait time, you must add the following registry keys:

   • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\cdm\Parameters
     Name: ScWriteWaitTimeout
     Type: REG_DWORD
     Value: (smart card write timeout in milliseconds)
   • HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\cdm\Parameters
     Name: ScWriteRetry
     Type: REG_DWORD
     Value: (smart card write retry count)

   [From XAE500R01W2K8X64095][#LA4060]

3. Servers might experience a fatal exception, displaying a blue screen, on Cdm.sys while using a smart card.

   [From XAE500R01W2K8X64095][#LA5293]

Fixes from Replaced Hotfixes

1. Attempts to reconnect to a disconnected session fail if made from a device that uses a smart card reader of a different type or make than the previous device.

   [From XAE500R01W2K8X64025][#253473]

2. Under certain conditions, attempts to reconnect to a disconnected session using a smart card can fail. This fix is disabled by default. To enable it, you must set the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDM\Parameters
   Name: EnableTransportIDPersistence
   Type: REG_DWORD
   Data: 1 to enable the fix; 0 to disable the fix

   [From XAE500R01W2K8X64025][#260771]

3. This feature enhancement lets you control whether users can copy files from their virtual environments to their user devices:

   When enabled, files and folders on mapped client-drives cannot be added or modified from within the session. Files and folders on mapped client-drives are available in read-only mode only.

   When disabled, files and folders on mapped client-drives are available in read/write mode from within the session. By default, the setting is disabled.

   To enable this feature:

   1. Configure client drive mapping (CDM) to be read-only. In the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdm\Parameters, create a DWORD value with value name ReadOnlyMappedDrive and value data 1.
   2. Configure the server-side clipboard to be read-only. In registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard, create a DWORD value with value name ReadOnly and value data 1.

   [From XAE500R01W2K8X64027][#211433]

4. Servers might experience a fatal exception, displaying a blue screen, on CDM.SYS with stop code 0x000000D1.

   [From XAE500R01W2K8X64039][#LA0020]

5. Copying and pasting graphics within Microsoft Excel does not work and the following error message appears:

   "Microsoft Office Excel cannot paste the data"

   [From XAE500R01W2K8X64039][#LA0302]

6. Servers might experience a fatal exception, displaying a blue screen, on Cdm.sys with stop code 0x000000D1.

   [From XAE500R01W2K8X64050][#LA0753]
