This is not really a Win32 Perl related blog entry, but a problem that my team recently experienced. I am adding this to our blog site with the hope that someone else experiencing the same problem may find it useful and (hopefully) save them some time troubleshooting.
Recently I ran into quite the system administrator emergency. Our Active Directory network started acting flaky. How odd it was that our servers were unable to talk with each other. Client machines were not able to boot onto the network. Attempts to access resources were confronted with ungodly long blocking wait times only to eventually fail.
Applications and services that normally execute flawlessly were suddenly cast into a bottomless pit of error massages such as:
There are currently no logon servers available to service the logon request
The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.
Of course the big question was why were there no logon servers available and why was there an attempt to compromise security? Needless to say it took several hours until my team could locate the root cause of the problem. Of course finding the cause is one thing, fixing it and understanding how the problem occurred is another.
