DESCRIPTION:
Aventail Clients And Windows Vista User Access Control

RESOLUTION:

Overview

User Account Control (UAC) is a Windows Vista security component that enables users to perform common tasks as non-administrators. Until the release of three hotfixes for appliance versions 9.0.0 and 9.0.1, as documented below, Aventail clients would not function properly if UAC was disabled.

Issues fixed

Isses fixed by the hotfixes listed in the Resolution section are as follows:

• Aventail Access Manager (AAM) fails to install or run if UAC (User Access Control) is disabled in Windows Vista.  (BugID: 35331/62901, 63758)
• OnDemand Tunnel will not provision on Windows Vista when UAC is disabled.  (BugID: 68887)
• OnDemand Tunnel does not disconnect after a user logs out when UAC is disabled in Windows Vista.  (BugID: 69834)
• OnDemand Proxy will not activate from the second time WorkPlace is accessed and from there on when UAC is disabled.  (BugID: 70332, 70079, 70080)
• OnDemand Proxy installs every time a user accesses WorkPlace when UAC is disabled.  (BugID: 70076)
• Script errors seen when RDP NAM accessed when ActiveX is disabled  (BugID: 70566)
• RDP NAM works first time, stops working after that  (BugID: 70574)
• Connect Tunnel installation fails on Vista SP1 when UAC is disabled, ActiveX enabled ,and Java installed  (BugID: 70047)

NOTE: Some of the fixes listed above were fixes for issues found during development of the hotfix.

Client-side requirements

The following criteria must be met on the client system in order for these hotfixes to work properly:

• Client system must be running Windows Vista Service Pack 1 or later
• Sun Java 1.6 or later must be installed and enabled
• Java caching must be enabled.  See Known Issues, below, for more information.

Known Issues

• If both ActiveX and UAC (User Account Control) are disabled on a client computer running Vista SP1, OnDemand Proxy can be installed but fails to activate unless Java is configured to keep a cache of temporary files on the local computer. To change the cache setting, go to Control Panel > Java > Temporary Internet Files > Settings > Keep temporary files on my computer.

Resolution

This issue was fixed by the following three hotfixes.  If you require support for Windows Vista systems where UAC has been disabled, all three hotfixes must be installed onto your appliance.

Workaround

If you are unable to use these hotfixes, reenable UAC in Windows Vista from Control Panel > User Accounts > Turn User Account Control on or off.
