My team is about to start doing it once a week. Ill let you know the outcome!!!
We normally reboot about once per month, and primarily because of Windows Updates, though I'm interested to hear if people are noticing performance gains by rebooting more often.
While I know that Windows servers *can* generally keep running for several weeks without a reboot, my experience is that the Solarwinds software experiences memory leaks, application instability, etc - especially in a sizeable environment - and a reboot is a great (if admittedly somewhat inelegant) way to keep things running smoothly.
Full disclosure: I openly hate on Microsoft.
Background: I've used Windows since about 1989, when it came for free on 12 5.25" floppies when you bought a copy of Excel 1.0. I got my MCSE in NT, 2000 and 2003.
So this is a distaste born of familiarity.
NO... Not unless there are patches which there usually are after patch Tuesday. My NPM/NTA/SAM server and it's SQL server is virtualized. This is my busiest poller:
