This has been a lingering problem for me that I can't quite figure out. We have a mac pro running server 10.6.8. It runs all our mac services including open directory. Every few days or so it stops accepting open directory logins and will not let anyone login to a machine until I do a reboot of the server. This makes me want to believe something in the software is messing up. Has anyone experienced this?
PS: Its only running snow leopard because we haven't wanted to move away from Work Group Manager. We still have a few snow leopard devices in our fleet.
