Security and Authentication Problems
VCM acts as a multiple-system administration tool and must have administrator authority on all the
machines that it manages.
The necessary authority might be accidentally removed or restricted. Common authentication problems
include changed passwords, dropped administrator access, or security measures such as a proxy server,
that are added without updating VCM. In addition to managed machine access, VCM also requires access
to its SQL Server database with the authority to insert, modify, and delete data.
Both kinds of access problems might reveal themselves in the user interface, in the VCM debug logs, or in
the operating system event log:
The VCM Collector service failed to start due to the following error:
The service did not start due to a logon failure.
SQL Server Problems
Nearly all data associated with VCM is stored in its SQL Server databases.
