I am having a similar problem and I am getting
Active Server Pages error ‘ASP 0126′
Include file not found
/crm/index.asp, line 2
The include file ‘/conn.inc’ was not found.
or
HTTP Error 500.24 – Internal Server Error

Most likely causes:
system.web/identity@impersonate is set to true.
Things you can try:
If the application supports it, disable client impersonation.
If you are certain that it is OK to ignore this error, it can be disabled by setting system.webServer/validation@validateIntegratedModeConfiguration to false.
Move this application to an application pool using Classic .NET mode – for example, %SystemRoot%system32inetsrvappcmd set app "Default Web Site/" /applicationPool:"Classic .NET AppPool"
(You can set "Classic .NET AppPool" to the name of another application pool running in Classic managed pipeline mode)
