Network VirusWall
Enforcer is unable to
register to Trend
Micro Control
Manager using
FQDN.
Verify whether the FQDN is able to connect to the Control Manager
server from a local computer. For example, instead of typing
https://IPAddress/controlmanager, type
https://fully.qualify.domain.name/controlmanager.
If you are unable to connect to Control Manager, please change the
Control Manager configuration to allow the connection. Network
VirusWall Enforcer 2500 can only register to Control Manager if
DNS is able to find the correct path to the Control Manager server.
Issues with quarantining and blocking endpoints

Network VirusWall
Enforcer 2500 is not
quarantining
endpoints whose
packets are infected
Check the Policy Enforcement Service configuration from
Policy
Enforcement > Policies
. Click on the Policy that includes settings
that quarantines endpoints with infected packets.
Network VirusWall Enforcer 2500 quarantines a maximum of 4096
endpoints and drops all network traffic from additional endpoints
(over 4096) whose packets are infected. Reconsider your
deployment plan to take into consideration the number of endpoints
in your network.

A endpoint that was
blocked because it
does not have the
latest Windows patch
remains blocked even
after running
Windows Update
Connect to "Microsoft Security Bulletin Search"
(http://www.microsoft.com/technet/security/current.aspx) and
search for the vulnerability name (for example, MS01-059) shown in
the blocking page. Download that specific patch and install it on the
blocked endpoint.
10
No page (or a blank
page) displays when
endpoint tries to
access Windows
Update
Try to refresh the current page, or close it and reconnect to the
Windows Update site. If doing so still does not solve the problem,
use another computer and connect to http://support.microsoft.com
and search for your problem.
