Maximum concurrent lesson restriction incorrect. 

Date: May 31, 2001

Version affected: v1.51
Does not affect copies of WBT Manager 1.51 downloaded after May 30, 2001.

Symptoms:

When attempting to launch a lesson in WBT Manager the following message may appear:

You may have only N lessons open in this course with a
status of "incomplete". You must complete some lessons
before you can take this one for credit.

This message is displayed when the course property Max concurrent lessons (on the Startup tab) is set to an integer value N and the student has N lessons in the current course that have a status of Incomplete (started but no finished).

If the course contains Instructional blocks this message may be displayed before the student has accumulated N incomplete lessons.

Correction:

This patch file contains a new version (1.51.0.3) of wbtman2g.dll which counts the number of incomplete lessons correctly (prior versions do not allow for instructional blocks with incomplete status).

To install the new version:

1. Upgrade to WBT Manager 1.51 if you have not already done so.
2. Unzip the patch file to a temporary directory on the web server.
3. Locate the existing copy of wbtman2g.dll on the web server. It should be in \winnt\system32.
4. Stop the web service to release the existing file.
   • Enter "NET STOP IISADMIN" at the console prompt while logged onto the web server as an Administrator.
5. Replace the existing copy of wbtman2g.dll with the new version from this patch.
6. Re-start the web services (NET START W3SVC).
7. Use the services applet in the control panel to re-start FTP and SMTP if desired.
8. Done

If you experience any problems after restarting the web services then perform a re-boot of the web-server.
