Thank you for your swift response.
The server was rebooted intentionally after a regular maintenance. There
are no significant errors reported in the event viewer. Similarly, TSM
activity log has recorded nothing since the reboot and no errors are
reported for the error occurred.
FYI below
Event Viewer: 
        Source: AdsmClientServiceTSM 
        Message: Scheduler halter right after the reboot.
Dsmerror.log:

Tell us what diagnosis you've done...
What's in the dsmerror.log and dsmwebcl.log files. Any indications of
problems in the Windows Event Log? (There may be more wrong in the
system than just TSM executability after that reboot.) Evaluate the
circumstances of the reboot: if it was actually a crash, or forced
reboot after a hang, there can be prevailing issues.
Is the dsmerror.log writable, in a writable directory, as directed by
your options file?  (If not, you'll have problems.)
