248 Frequently Asked Questions
What ports do the IT
Assistant services use to
communicate? How can I
change the port
assignments?
Port 2607 enables the IT Assistant UI to communicate
with the IT Assistant Connection Service. Port 2606
enables the IT Assistant Connection Service to
communicate with the IT Assistant Network Monitoring
Service. You can change these port assignments when
installing IT Assistant using customized settings. If you
do not change the port assignments during customized
installation, you must use the registry to reassign port
numbers. See also "Ports Used by IT Assistant and
Associated Agent Application" in the Dell OpenManage
Security and Installation Guide.
If I have multiple
protocols bound to one
network card, IT
Assistant displays
multiple entries for that
network card under
Network Data on the
Summary tab of the
systems window. This
leads me to believe that I
have more network cards
installed on the system
than are actually there.
Why does IT Assistant
display these multiple
entries?
This situation is most likely to occur when using pure
SNMP to communicate with the managed system. Most
of the summary information shown is taken out of tables
across the appropriate MIB file. In this case, network
information is taken from the MIB2|Interfaces table.
Binding multiple protocols to a single network card adds a
row to the MIB file interfaces table for each protocol. IT
Assistant then pulls all rows from this table. Because there
is only one physical address per network card, you can use
the physical media access control (MAC) address to
ascertain how many network cards are actually installed.
Why does DCOM
generate event log
messages when it fails to
establish communication
with managed systems?
This problem is a known issue with the Microsoft WBEM
implementation. DCOM logs an error every time a
remote connection fails. If CIM is enabled, IT Assistant
tries to connect to every CIM agent that resides at an
address that can be contacted using the ping command. If
the user name and password do not work or if there is no
CIM agent, DCOM adds an error message to the event
log.
Why are IT Assistant
services unstable on my
system running Windows
2000?
IT Assistant services may exhibit instability on Windows
2000 SP3. See the Microsoft Knowledge Base Article
813648: "Random Access Violations When Multithreaded
Applications Call the setlocale Function."
