Working with a client that is trying to establish a reboot policy for their Windows systems, and the direction another group has suggested is a reboot every week on Sunday nights.
In my experience, this is way overkill - I suggested if they felt a scheduled reboot was needed, that for the most part monthly or quarterly would be perfectly acceptable.
The caveat here is that this is O/S and application dependent - if there are apps that are 'leaky' that should be evaluated and the reboot schedule modified to fit the app, but generally that a weekly reboot is unnecessary. In some cases they are still running Win2K and those servers probably need to reboot and cleanup more often than the Win2K3 servers.
The response was 'what does it hurt' and the answer is nothing, I guess, but it feels like an awful lot of effort that is probably not necessary.
If you have thoughts and/or suggestions, or feedback as to what your policy is, I'd love to hear it.
