Spent all morning with a tech trying to recreate our door access system from scratch. The machine that it lived on before had a drive failure, no recoverable data (including all the backups and database, which only lived on that machine). Finally got it all running right, but everyone that walked out of the office had to go to the front door to get in since their access cards didn't work anymore. I'll be firing off a backup of this system later this afternoon so we don't have to go through this again.
Didn't that system give you trouble a while back, too? I seem to recall hearing about it.
