been racking my head about this one for a while now.
Windows 7 is randomly producing a "There are currently no logon servers available to service the logon request".
Infastructure is Windows 2008 R2 DC's, DNS correctly configured and assigned via DHCP. 600+ workstations. Rebooting them for the most part resolves the issue but not always.
Any ideas how to put a permenent stop to this and what might be causing it?
