We are serving a classic ASP web application for ~4,000 sites on IIS 7.5 on a webfarm of 8 virtual 2008 R2 servers. IIS is using shared config in a DFS configuration. the application pools are divided somewhat equally among the sites. We are having an issue with the application pools failing intermittently to create objects and recognize script engines. Active Server Pages error 'ASP 0129' Unknown scripting language /mp_admin/upload.asp, line 1 The scripting language 'VBScript.Encode' is not found on the server. _________________________________________________________________ 502 - Web server received an invalid response while acting as a gateway or proxy server HTTP Error 500.0 - Internal Server Error ______________________________________________________________________ Server object error 'ASP 0177 : 800401f3' Server.CreateObject Failed \\CODER\DEVERSION\MANAGER\../mp_includes/stylesheetsettings.asp, line 161 800401f3 Microsoft VBScript runtime error '800a000d' Type mismatch: '[string: ""]' /mp_manager/menu.asp, line 272 The fix thus far has been to: 1) recycle the app pool 2) recycle IIS 3) reboot the webserver we have been all over learn.iis.net; technet; to look for configuration issues once the app pool goes down failed trace routing does not provide any more information that what you see above - event logs also do not contain anymore info than what is shown above We are wondering if it is how IIS is processing the shared config. DFS is set up in a star/spoke configuration - the vbscript.encode error is directly related to a client updating pages on their websites.
