DSREPAIR -XK3 -  How to use it and why you would use it
Removing External Reference Links and Recreating them.


On the NetWare Platform:

1.  Load DSREPAIR -XK3 | Advanced options | Repair local DS database | Check local references = Yes | F10 to start the repair.  This goes through all of the server's backlink attribute timestamps and sets them to zero.
2.  Save the repaired database and exit from DSREPAIR completely.  
3.  Run the backlink process to rebuild the backlinks. At the server console prompt type:

SET DSTRACE=+BLINK   (+ sign turns DSTRACE on as well)

This last process will update the timestamps on those objects that are still valid. Those that are not updated are purged the next time the janitor and flat cleaner processes run.

On the Windows NT\2000 Platform:

1.  Start the NDS Services applet from the Control Panel
2.  Highlight DSREPAIR.DLM
3.  Enter -XK3 (must be in CAPS) in the Startup Parameters field and Click START.
4.  Click Repair in the menu and then Local Database Repair
5.  Make sure "Check Local References" is checked and then start the repair.

To start the backlink process, do the following:

1.  Start the NDS Services applet from the Control Panel
2.  Highlight DSTRACE.DLM and then Click START
3.  Click Edit in the menu and then Options
4.  Uncheck everything except the Backlinker and Backlinker Detail filters.
5.  Click OK
6.  Go back to the NDS Services applet and highlight DS.DLM and then Click Configure.
7.  Go to the Triggers tab and Click Backlinker.

On the UNIX Platform:

1.  At a command prompt, type ndsrepair -R -Ad -XK3  (ndsrepair and it's switches are case sensitive)
2.  Type ndstrace and Enter
3.  Type set ndstrace = *b

Additional Information

The problem is the backlinks to the externally referenced objects have gone bad.
