503 Error after running Configuration Wizard

Issue:

When installing or upgrading a SolarWinds product on a server that is also hosting Microsoft Exchange (or potentially any other non-SolarWinds 64-bit application), a failure to update IIS website configuration settings triggers a 503 error as the Configuration Wizard attempts to finish its website-related configuration work. The same failed configuration also leads to a dying SolarWinds Application Pool.

Solution:

This issue arises when a non-SolarWinds 64-bit application installed on a SolarWinds host fails to specify that it is a 64-bit application. More specifically, the configuration error occurs if a 64-bit application includes a call to a .dll in the <globalmodules> section of applicationhost.config without specifying precondition="bitness64".</globalmodules>

<globalmodules>The fix is to add the bit-ness precondition to Exchange any other 64-bit application and then restart IIS.</globalmodules>

For more information, see "How to Run a 32bit Web Application on SBS 2008/2011 Standard" at technet.com.

Expected Result

Assuming all 64-bit applications on a SolarWinds host correctly declare their bitness, the Configuration Wizard should complete successfully
