Using samba as a DC.
Recently I've been getting a crap load of issues.
1: I keep getting this error on my workstation:
Automatic certificate enrollment for local system failed to contact the active directory (0x8007054b). The specified domain either does not exist or could not be contacted.
Enrollment will not be performed.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
2: My workstation once totally lost contact with the DC, it was impossible to have it communicate at all, I had to reimage the machine, I removed from domain and was unable to rejoin - just kept saying it could not find it.
3: another workstation decided to no longer be able to logon to the domain. I disjoined it, and now it wont let me. In fact, if I type \\dcname I get the same error. Says "the account is not authorized to log in from this station". whatever. I never did anything.
I tried to remove the machine account, readd it... no luck.
WTH is going on with this dc?
Running FC5. (yeah yeah I know, but its too much of a huge deployment task to upgrade my main production server)
