At risk of revealing my shortcomings when it comes to personnel management, I am seeking help here to disable the MSN Messenger on a networked workstation. The user of the workstation is abusing the service and, believe me, when I say that there are more than enough issues currently running that a dispute over this is something I can well do without.
I have uninstalled Messenger (only for it to be reinstalled) and despite trying many of the weird and wonderful remedies brought up by a Google search (assorted registry edits etc) I have been unsuccessful in preventing its continued use.
The user of the workstation is not an advanced computer user so I reckon if I can successfully block the necessary ports in the Firewall I shall be able to prevent further use.
Can someone please suggest how I might go about this, bearing in mind that I am not a wizz when it comes to firewall settings etc, so I ask that the instructions be fairly explicit!
Throughout the network we use the Messenger service for pop up messages so I do not want a remedy that is going to render this ineffective!
I shall welcome any advice and assistance, thanks, Roger
