Why do I get a Java out of
memory exception?
When managing an environment with more than 2000
devices, increase the amount of memory allocated to the
Java Runtime Environment (JRE) heap.
NOTE: The memory should be increased on the system from
where you access the IT Assistant Management Station.
To do so, close the IT Assistant browser session and go to
the Java Control Panel. The panel is located under the
Microsoft Windows Control Panel or the ControlPanel
executable in the bin folder of the JRE installation on
the Linux system.
Click the Java tab and in the Java Applet Runtime
section, click View.... Click in the Java Runtime
Parameters area and type:
-Xmx384M
Why do I get a host name
mismatch warning when I
try to access the IT
Assistant user interface?
This warning appears if the web address that you use to
connect to IT Assistant contains a different host name
than the one that was used to install IT Assistant. For
example, if you installed IT Assistant using the host
name sysadmin3 with an IP address of 133.143.157.30,
the warning appears if you log in to IT Assistant using
the IP address. However, if you log in to the remote
device using the system name, sysadmin3, the warning
does not appear.
Why don’t I get a Login
prompt when I login to IT
Assistant from a desktop?
IT Assistant uses the operating-system credentials of the
currently logged-in user and automatically logs you in to
IT Assistant. See the section about Single Sign-On in the
Dell IT Assistant Online Help for more information.
Why does the Windows
NT LAN Manager
(NTLM) authentication
fail when I attempt to log
