Run SFC /SCANNOW from an administrative command prompt.

If no help, it may be fastest and simplest to run a Repair Install
This should not affect personal data or installed programs, but a backup first is always a good idea.

taskeng.exe is part of Task Scheduler, but that is almost all we get as a hint. Causes are that many that all I can suggest is to perform a search for "appcrash taskeng c000071b" to get troubleshooting hints.
One frequent tip is to check AntiVirus etc. software for known issues.

Seems to only happen under the administrator login. Not sure where to look. Google's got nothing, really.
Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

Any log messages before that crash or after? Like same in all cases?

Most of the hits I got point to malware; specifically redirect Trojans.
Run Roguekiller and see what it finds:

Good suggestions -
SFC came back clean. I am NOT doing a repair install on a Small Business 2008 server. LOL just sayin.
I will follow up with log messages, if any. Working Roguekiller now.
Elixir2Author Commented:
Roguekiller is also clean.

Windows Error log first shows "Error 1000 Application Error" which contains the same information in the OP above.

But at the same time - exactly coinciding times on the error log - we see "Error 1004 CertificateServicesClient - Certificate Services Client Provider pautoenr.dll raised an exception. Exception code 3221225477." No further details.

This is new to me and looks promising. What next?

Working this link. Due to multiple reboots and possible need to be on-site, resolution might not happen today.

Looks promising, but "This is an involved process with several reboots".
