Service Detection [modified]

[Darkness84]

I have written a service that will be run on mutiple computers connected to the same network. However if the service is already running on one computer I don't want it to run on the other computers. Does anybody know if this is possible? -- modified at 18:34 Wednesday 7th March, 2007

Most things are possible given enough time and resources. The problem is that you will have independent processes running on independent machines that know nothing of each other. Somehow you have to get them to know about each others run status. The most common way of doing this is for them to connect to and query a server. This server can keep track of which computer is currently running the service. Hopefully that helps. Phil

Thank you very much. Your post was most helpful. I created a table in the database that has one column called Running which I set to N. When the service first starts up it queries this table. If N is returned the service sets it to Y and it can start. If Y i returned the service cannot start. When the service which is running stops, it sets the row back to N.
