Slow Performance on Windows Server 2008
This information is deprecated. Products running on SolarWinds Platform version 2017.3 cannot install on Windows Server 2008.
If Orion is installed on Windows Server 2008 and there are any devices on your network, between your SolarWinds Platform server and your database server, that do not support RFC 1323, the TCP window size auto-tuning feature of Windows Server 2008 may prevent your SolarWinds Platform server from successfully connecting with your SolarWinds Platform database.
This TCP auto-tuning feature is intended as a network-sensitive restriction, applied by the receiver—your SolarWinds Platform server—on the amount of data it is allowed or able to receive. If any devices along the network path between your SolarWinds Platform server and your SolarWinds Platform database do not support the TCP window scaling detailed in RFC 1323, the allowed size of the TCP window in packets sent to your SolarWinds Platform server may not match the TCP window size reported by packets sent from your SolarWinds Platform server. This mismatch may lead to failed connections between your SolarWinds Platform server and your SolarWinds Platform database. The following procedure disables this TCP auto-tuning feature, resetting the TCP receive window to 64kB.
- Click Start > All Programs > Accessories.
- Right-click Command Prompt, and then click Run as administrator.
- If you are prompted by User Account Control, click Continue to open the elevated command prompt.
- At the prompt, enter the following: netsh interface tcp set global autotuninglevel=disabled
- Close the command prompt window, and then restart your SolarWinds Platform server.
In some cases, having User Account Control (UAC) enabled on Windows Server 2008 can lead to installation errors. For more information about disabling UAC, see the article "Disabling User Account Control (UAC)" in the SolarWinds Knowledge Base.
