Hi Brandon,

Please can you write a small script that attempts this ExecQuery, then
ensure it hangs three times on the rogue machine and works three times
on a good machine, then post it here.

Connect to the rogue machine as a domain admin, right-click "My
Computer" then "Manage"; does the security log instantly appear on screen?
