Start and Stop Pco Agent

Good morning experts,

  we have connections beetwen Emerson DCS - DELTAV OPC and MII using SAP PCo 15.0

Everything was fine since Managment decided to start and stop Agent Monitor during a window in order to avoid PCo Tags Browsing towards DCS.

We are using Windows Tasks scheduler to start and stop services, but it seems that start and stop result is different from using PCo console because now we have the error below.

Any Ideas?

Thanks and best regards
