One of the server was showing status as Stopping since a long.

1. I killed the process from Task Manager

2. Siebel Services are getting up and showing up in the MS Services
3. Not showing as available server when checked by command line / application (Site Map -> Server Management)
4. Checked logs
5. found the issue as - SBL-SMI-00147: Version check failed because: Error: cannot get version of installed components (ENU sia)

Reason : File sslcver.dll got corrupted from ROOT\BIN\ENU

Resolution : copy file (sslcver.dll) from ROOT\BIN or ROOT\BIN\ (in our case it was ROOT\BIN\FIN as we have Finnish as one of the language) and put it in ROOT\BIN\ENU

Restart Services

NOTE: This may happen for ENUSIA or SIA
