If there are multiple Internet Information Services (IIS) web applications running on multiple application pools, there may be multiple w3wp.exe processes running on your server.  This can make it difficult to identify which process corresponds to the TIBCO Spotfire Web Player.

How to determine which w3wp.exe process corresponds to the TIBCO Spotfire Web Player.

To identify which process corresponds to the TIBCO Spotfire Web Player, follow these steps:

1) Start a command prompt as an administrator:
  a) Click Start > All Programs > Accessories.
  b) Right-click "Command prompt".
  c) Click "Run as administrator".
  d) If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.

2) Run the following command:

 %windir%\system32\intesrv\appcmd list wp

3) This will return something like:


4) Find the entry with the Web Player application pool in parentheses. The number in quotes is the PID (process id) of the Web Player's w3wp.exe process. Example:

 WP "4196" (applicationPool:TIBCO Spotfire Web Player X.X.X Pool)

When viewing the active processes in "Task Manager" you can enable the "PID" column (Right click on columns and select "Select Columns", select "PID" check box, click "OK") and find the w3wp.exe process whose PID value matches that found in Step 3.
