Chapter 3 Installation and Setup
• Has the certificate expired?
• Does the name on the DTX Control server certificate match the name the DTX Control client used to access the DTX
Control 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 the DTX Control 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 DTX Control hub server and the DTX Control 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 DTX Control 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 DTX Control client, open a client session. 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 DTX Control 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 DTX 5000-CTL Management Appliance is installed on a server
that is set to an invalid time. When a DTX Control client that is set to a valid time connects to the DTX Control
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.
To create a CSR:
1. Click the System tab - DTX Control.
2. Click Certificate in the side navigation bar. The DTX Control Server Certificate Properties window will open.
3. Click Get CSR. A File Download dialog box will appear.
4. Click Open. The CSR is downloaded and displays in the configured text editor.
-or-
Click Save. The Save As dialog box will appear. Select a directory and filename and click Save to save the CSR.
5. Submit the CSR generated request to a CA to obtain a signed server certificate.
6. Update the DTX Control server to use the certificate created by the CA.
Managing hub and spoke server certificates
When a spoke server is registered with a hub server, a certificate trust relationship is established between the two
servers. Certificate information must match on the hub server and the spoke servers for communication to take place
between the servers. If the spoke server certificate is subsequently changed, a certificate mismatch will occur.
To update the certificate of a spoke server on the hub server:
NOTE: Certificates may only be viewed by DTX Control administrators and user administrators.
1. On the hub server, click the System tab - DTX Control.Server will automatically be selected in the top navigation bar
and the name of the DTX Control hub server will appear at the top of the side navigation bar.
2. Click Spoke Servers in the side navigation bar. The Spoke Servers window will open.
