We are running an old training system based on Windows Server 2003 and XP-clients. The solution is rather simple with four servers, two of them beeing DC:s. Everything is preconfigured and that goes for backup scheme as well. The backup software is Symantec BackupExec 2010. The scheme is a standard GF-F-S routine with full backups running once a week on Sundays. The other six days run differential backups.

Now let's say in a worst case scenario, a server crashes on Saturday and we have to restore it from backup. The last backup will then be six days old and thus it will come online with six days old configurations. Will this pose a problem for the other servers or will the recovered server "get in line" eventually?
