" Installer detected that your local IIS Web Server is not operational . Please verify that IIS 6.0 or later is installed and corresponding services are up and running. Then click Next."

You are able to verify that you have all of the SEEMS pre-requisites met, and IIS is running.

" Installer detected that your local IIS Web Server is not operational . Please verify that IIS 6.0 or later is installed and corresponding services are up and running. Then click Next."

Cause

If you have moved the C:\INETPUB folder to another drive (D: for example), there will be a failure to recognize the IIS service due to a registry entry which points to INETPUB being on the %SystemDrive%

Resolution

Export a backup of the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp

Modify the following registry entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp\PathWWWRoot
Change %SystemDrive% to the drive letter INETPUB is located on.

No reboot is needed.  Attempt to install Symantec Endpoint Encryption Management Server again.  IIS should be detected properly.
