 ====== Network Troubleshooting ======
 In order for Windward Software products to function correctly in a network environment, there needs to be adequate network infrastructure.  By network infrastructure, we mean a professionally cabled network with reliable network cards and switches.  A properly configured server, DNS and TCP/IP protocol for our applications and other network services will be required.  If things are not working as they should, this document may give you some ideas on what to check and consider.

   * Are there any patches available for the server hardware?  Firmware such as RAID card, network card, BIOS?
   * Could line voltage be an issue?  Any large motors, compressors or welding devices nearby?  You may want to consider some power conditioning.
-  * Check for pending Windows updates on all workstations/servers involved.  Strange things can occur when updates have not been applied a server degrades into a "reboot pending" state.

   * Check for bad or failing ports on switches that are not consistent (Even new ones can fail)
   * Ports auto-detecting incorrectly (ie: 10Mb detected on the switch when the server is transmitting at 100Mb)

   * Is there any third-party software installed such as State or Provincial level tools that could impact VPN or network access?
   * Have you swapped internet providers and left old DNS information hardcoded on workstations?  This can be overlooked and can cause 30-second timeout delays while DNS fails over to a working DNS server.  Due to the round-robin and caching nature of DNS, System Five will work sometimes and have a long delay at other times.
+  * Server restore points being made can cause the database service and System Five to become unresponsive while the restore point is being created and can cause database timeout errors.  Although great to restore the server to a known point in time, do not configure restore points to be created automatically during production hours of the business.
+  * Intrusion Prevention Software (IPS) which can cause network overhead and slow performance doing scans.
 ===== Have a Plan B =====
-When a local network event takes place, often IT resources get solely placed into troubleshooting and healing the network.  This is a great primary action but consider and start moving a Plan B in the event that healing the network does not work.  Restoring from backup to a different server may not seem like a great plan now.  But when it can take days to get parts for a failed server resource, operating on a slower second option will seem like a good option to have.

+<note tip>Example:  Restoring from backup to a slower server may not seem like a great plan at the beginning.  When it can take days to get parts for a failed network component, operating on a slower second option will eliminate downtime if it is available.</note>
