This guide is intended for new installations or troubleshooting existing installations. Once you are sure you have met the prerequisites, you can begin the LabTech installation. Refer to the LabTech Installation instructions for step-by-step instructions. IMPORTANT: It is very important that you complete the following Installation Prerequisites prior to installing LabTech 2012; otherwise your installation may fail or some components of LabTech 2012 will not function correctly! Server Requirements The server requirements will vary based on your environment (e.g., probe use, number of probes, number of agents, etc.). Depending upon actual usage, the hardware and software required may be more or less than what is recommended. The following is a recommendation based on the number of LabTech agents in the following sizes: 500, 1000, 2500, 5000, 10,000 and 20,000. Due to performance issues, a physical server is recommended, especially with over 1000 agents. You can also download a copy of the Scalability Guide from the LabTech website. NOTE: LabTech CANNOT be set up on Windows Small Business Servers (SBS), Windows Essential Business Servers (EBS), Windows 2008 Foundation Edition (FE) or Windows 2012 Server. Refer to the Microsoft Windows Server 2012 Timeline KB for additional information. 27A InstallationPrerequisites.docx 1

When the LabTech server contacts the licensing server, your licenses are tied to your IP address. If you do not use a static IP, you will have to contact LabTech occasionally to provide us with your IP for the licensing. In addition, the Web Control Center relies on the IP address. If your IP address changes, you will not able to access the Web Control Center unless you modify your registry to recognize the new IP. Software Requirements The following software is required prior to installing LabTech. If you need additional information on how to configure the following, please refer to the 2003 Windows Server Configuration and 2008 Windows Server Configuration sections later in this document. IIS 6.0 or higher..net 3.5 is required on all systems running the Control Center, including the LabTech server; otherwise, many of the new features will not be functional and may crash. Microsoft Windows Server 2003 or 2008 (32-bit or 64-bit) (2008 R2 recommended) o If using 2003 Server, Service Pack 2 MUST be installed. o If using 2008 Server, you must do the following: Install IIS 6.0 Compatibility (all features) Add ASP and ASP.net Unbind IPv6 from your NIC(s) before starting the LabTech installation. Disable UAC on the server, if enabled. LabTech is installed with MySQL a and only supports version 5.5.xx with a minimum build of a. Other versions are not supported. NOTE: Ensure that these applications have been installed and configured properly prior to beginning the installation of LabTech. LabTech cannot be setup on a server with any of the following software installed: Microsoft SharePoint Services (any version) Windows Update Services (any version) 27A InstallationPrerequisites.docx 3

4 LabTech Installation Prerequisites Apache Web Service (any version) IMPORTANT: It is recommended that the LabTech server is a dedicated server/virtual machine without any other software/websites loaded on it. The exception to this is Antivirus. This is due to the changes that may be made to the default behavior of IIS and other Windows settings. WARNING: This may affect our Support department s ability to diagnose an issue and support may be refused if other software/websites exist on the same server. Internet Requirements Port Forwarding You must have Internet access and be able to reach for licensing validation. LabTech only needs two TCP ports (70 and 80) forwarded to the LabTech server for basic operations. For more advanced options, you may want to use SSL and VNC Quick Connect; therefore these ports will also need to be forwarded. The following ports need to be forwarded from your WAN IP to your LabTech server: Port 70 TCP: Redirector communications without tunnels Ports UDP: Tunnels and Redirectors Port 80: HTTP Normal communications Port 443: HTTP SSL Normal communications (optional) Ports TCP: Connecting via HTTP or to use VNC from the Web Control Center. Open ports beginning with and ending with four times the number of total technicians using LabTech (e.g., If there are 25 technicians, then there are 25x4 (100) simultaneous sessions). So, ports should be open. These ports are also needed for mobile devices if you plan on using VNC. Ports UDP: Tunnels and Redirectors, only when advanced routers are blocking and not at the LabTech server, at client and agent locations or where the router in front of the Control Center is blocking. Local Machine Access: o on any port from using any protocol should be opened (local machine access) o Port UDP from local LAN computers ( ) (local machine access) NOTE: If you change the default TCP port 70 in the Dashboard > Config > System to another port, then you would forward that port + 5 (e.g., 90-95) Restricted Ports The following are restricted ports for Control Center connections from outside your network. Make sure the users are accessing via SSL by enabling SSL on the MYSQL server and checking the Enable SSL checkbox on the Control Center login window. For maximum security, do not forward these ports. If for some reason you need to forward these ports, limit the access to a list of IP Addresses Control Center Redirector ports 27A InstallationPrerequisites.docx 4

5 LabTech Figure 1: Sample D-Link Router DNS Configuration External DNS Configuration You will need to register a FQDN for the LabTech server with your registrar (e.g., server.labtech.com) o o o o o The WAN IP Address, of the LabTech server, should be used for the FQDN. The agents will use this to connect to the LabTech Web Control Center. The FQDN will be used in the redirector config. It is also recommended that an SSL is obtained for this domain. A wildcard certificate may be used. Internal DNS Configuration You will need to setup a new zone (matching your external domain name) if your local domain name is different from your external domain name AND your router/firewall is not setup to route your LAN traffic back from the WAN interface to the LAN interface (e.g., sonic walls have to be manually setup to do this). If you need assistance with creating a new zone and adding the correct CNAME and A Records, please consult your DNS software guide. 27A InstallationPrerequisites.docx 5

6 LabTech Installation Prerequisites o o How to Install and Configure Microsoft DNS Server BIND Add the www and other records you need and set them the same as they are on the external DNS server. Add a LabTech record and use the local IP address of the LabTech server. NOTE: This will let your internal hosts connect to the LabTech server directly and external hosts will connect to the router and be forwarded. Mail Configuration Backup Mail Server You will need an address to use for support tickets. Any mail sent to this address will be downloaded to the LabTech server and each message will be added as a support ticket. After downloading, the (s) will be deleted from the mailbox. Due to security changes within Exchange 2007/2010, you will need to set up an additional SMTP connector for mail with the following: Allow anonymous connections. Use the LAN IP of your LabTech server to restrict anonymous connections for the new SMTP Connector. For more information about SMTP Connectors see the Microsoft TechNet Guides: o Exchange 2010 o Exchange 2007 A backup mail server is strongly recommended. This ensures reliability and keeps your business running smoothly. 1. Install a SMTP server on the LabTech server. 2. Ensure the secondary mail server is running on the same SMTP port as the primary mail server. If the primary mail server cannot be reached for any reason, the second attempt will go to the secondary mail server. NOTE: The easiest way to configure a second SMTP server is to enable the built-in SMTP server in IIS. 3. Set the secondary server to listen on the same port as the primary mail server. 4. Allow Everyone to Relay. 5. Allow Everyone to Connect. 6. Configure Smart Host to be the primary mail server. IMPORTANT: Do NOT forward port from router to this SMTP server on LabTech server. Antivirus and Anti-Spyware All antivirus and anti-spyware applications on the server need to be disabled before installation. 27A InstallationPrerequisites.docx 6
