SymProxy Automated Installation

  • Artikel

These steps along with the Install.cmd script below can help automate the installation of SymProxy to a default IIS installation. You will likely need to adapt these steps to the specific needs of your environment.

  1. Create D:\SymStore\Symbols folder.

    • Grant Read to Everyone

    • Grant Read\Write to the SymProxy App Pool user account (Domain\User)

  2. Share D:\SymStore\Symbols as Symbols.

    • Grant Read to Everyone (or be more specific)

  3. (Optionally) Create an empty file called index2.txt in D:\SymStore\Symbols.

  4. (Optionally) Create an empty file called %WINDIR%\system32\inetsrv\symsrv.yes. This accepts the EULA for the Microsoft Public Symbol Store.

  5. Determine the parameters for Install.cmd and run it.

  6. Configure the clients symbol path using the server name that you created.

    SRV*\\MachineName\Symbols*https://MachineName/Symbols

The Install.cmd script requires 3 parameters:

  • Virtual Directory path (e.g. D:\SymStore\Symbols )
  • Username (for the Application Pool)
  • Password (for the Application Pool)

To clear the MIME Type inheritance, an XML file is needed to drive the associated AppCmd.exe command. Place the staticContentClear.xml file shown below in the same folder as the Install.cmd script to achieve this result.

Example Install.Cmd parameter usage:

Install.cmd D:\SymStore\Symbols CONTOSO\SymProxyService Pa$$word

Install.cmd

@echo off

SET VirDirectory=%1
SET UserName=%2
SET Password=%3

            <clear />
        </system.webServer-staticContent>
    </CONFIG>
</appcmd>

Testing the SymProxy Installation

The system should now be ready to acquire and serve files. To test it, start by restarting the IISAdmin service by running iisreset.exe. This will reload the ISAPI filter with the current IIS and SymProxy configuration.

Configure a debugger to use this symbol path:

srv*\\MachineName\Symbols*https://MachineName/Symbols

If MissTimeout is enabled (it is set to 300 seconds by default), running the .reload /f command twice should result in much faster execution the second time.

To view the location of the PDBs being referenced, use the lm (list modules) command. The path to the PDBs should all begin with \\MachineName\Symbols.

If directory browsing is enabled on the web site, browse to https://MachineName/Symbols to see the files that are cached.

Open the Performance Monitor and view the Symbol Proxy counters.

Open the Event Viewer and view the Microsoft\Windows\SymProxy events.
