We experience this issue for few days now, only.
After the workstation is imported in the tree, automatically, at logon, the last thing in the zenwsreg.log file is:
Entering ZENWSREGUnreg
And the workstation unassociated itself from the tree, deletes the registries that point to the workstation object in the tree.
Thus we cannot remote manage the workstations anymore.
Why is this happening, how can I fix it.
