Hi Leslie:
We are also facing same issue in our production system. However this note cannot be applied. In RZ20 the data is being reported but while checking in DBACockpit the nodes are greyed out.
We are using SAP ECC 6 EHP5/NW 7.02 SP08. MS SQL 2008 R2 10.50.1600.
Correction Instructions in this note are only for NW 7.40. I have not tried server restart but application restart has not helped.
Thanks.
