• Has the certificate expired?
• Does the name on the DSView server certificate match the name the DSView software
client used to access the DSView server?
A Security Alert dialog box will appear if the answer to any of the three questions is No. To
prevent the Security Alert message box from appearing when you connect to a the DSView
software hub server, all three questions must be answered Yes. When a Security Alert dialog
box appears, you have the following choices:
• If you click Yes, a connection will be made with the DSView software hub server and the
DSView software login window will appear, but the Security Alert dialog box will
continue to appear each time you connect to the hub server.
• If you click No, a connection will not be made with the DSView software hub server.
• If you click View Certificate, you may install the certificate; see below.
To correct certificate security alerts for client and hub server connections:
1. From the DSView software client, open a client session; see Opening a client session on
page 20. The Security Alert dialog box will appear.
2. Click View Certificate. The Certificate dialog box will appear.
3. Click Install Certificate. See the Internet Explorer documentation for more information.
4. Once the certificate is installed, ensure that the time setting on the DSView software client
PC is within the Valid from...to... dates and that the Issued to and Issued by fields exactly
match.
Invalid to...from dates typically occur when the DSView software is installed on a
server that is set to an invalid time. When a DSView software client that is set to a
valid time connects to the DSView server that is set to an invalid time, the following
warning will appear in the Security Alert dialog box: “The security certificate date is
invalid.”
Serial session security alerts
The Serial Session Viewer, which is used during a serial session, is a Java-based applet. Three
certificate tests are performed by Java when the DSView software connects to a serial device:
• Does the serial device trust the certificate issuer?
• Has the certificate expired?
• Does the name on the serial device certificate match the name of the DSView software hub
server certificate?
