I was looking around on my RRAS box at work, checked a couple of things, and one of the programs (uninstall wizard) refuses to close down. Start - Shutdown now has the machine stuck and I can't launch ...

We have 2003 SP1 and 2003 R2 (SP1 implied) boxes that I keep patched monthly, and I haven't seen this issue. As a workaround, could you run a script nightly that restart the Terminal Services service?

The FileVault security system, introduced many years ago to macOS, prevents someone from starting up or restarting your computer and gaining access to its startup volume, which is encrypted.
