When starting the aserver from the aserver.bat file the following error is displayed:

"the system cannot find the path specified"

When stating the aserver from services the following error is displayed:

Could not start the RSAAserver service on the Local Computer

Error 1053:  The service did not respond to the start control request in a timely fashion.

The default ClearTrust installation directory on Windows is "C:\Program Files\RSA\ClearTrust 5.5.3".   The directory names in these directories exceed the 8.3 DOS file name size.  In the aserver.bat file and the registry entry that is used to start the ClearTrust servers the JAVA environment must use short file names as in this example:

set CT_ROOT=C:\PROGRA~1\RSA\CLEART~1.3

Ensure that the path to CT_ROOT uses the correct 8.3 short file names for the directory.  If the directory has been copied or renamed the directory names in the batch file may not be correct.  At the command line run DIR /X to list the short file name for each directory in the path.   Modify the aserver.bat file accordingly.

C:\Program Files\RSA>dir /x
 Volume in drive C has no label.
 Volume Serial Number is 849E-E1AA

Ensure that the Windows volume where ClearTrust is installed is able to support 8.3 file names.   This feature is enabled by default, but can be disabled for some volumes.  See Microsoft Knowledge Base Article KB121007
