Managing a network with a C# client/server app ?

Hey,

I've been working on an application for a while now that allows me to perform actions on computers in a network, so far it can clean the PCs by launching CCleaner, uninstalling programs that shouldn't be installed and updating flash, etc.

The program uses a client-server structure with the client being a windows service and the server a normal forms application.

Now I have the following problems.

- How can I install the service on all 88+ PCs in the network in 1 go, I tried using a vbscript that tries to access the remote PC and install it but that failed.
- When ran as a service the app seems to be unable to reboot/shutdown the PC, perhaps also unable to perform one of the other tasks, yet it successfully connects to the server


Hope people here can help me out.

Thanks for your time, Xeross

P.S.: If you need any source code I'll be happy to provide it.
