After fresh installation of EntM on clustered W2K12 server/SQLServer (WSFC), there is no ac-env in environment panel of idmmanage and EntM WebUI shows error of "Web page not found".
From installation log, the connection to database was timed out on database table registration and it caused some tables were not created and data was not registered.
It seems that clustered SQLServer was stopped due to a problem of drveng network interception, as PIM endpoint is installed as a part of EntM installation and it happens before database registration.
PIM 12.9 SP2 / Windows 2012
1. Uninstall EntM, JBoss and remove EntM database once
2. Install PIM endpoint 12.8 SP1 CR1
3. Add DWORD registry value of DisableNetworkInterception=1 under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\drveng\Parameters key
This should avoid the problem of drveng network interception during EntM installation
4. Recreate EntM database and reinstall JBoss and EntM.
