Which version of EEPC?
That file is one byte size and legitimate attribute.
Please post full SbClientLog.txt. Is hard drive encrypted? Pre-boot present?
If not, reinstall client (SBsetup.exe -uninstall).
For corrupted database, export that machine object first, then perform offline database maintenance with orphan check and "cleanupmachinegroup" SBADMCL command.
Running EEPC 5.2.3, hard drive is encrypted, Pre-Boot is present, using AutoBoot user to authenticate.

Maybe you have damaged object attribute set. Restore object from backup, or reinstall client.
sounds like the name attribute is corrupt - have you been using the same account for multiple simultaneous logins maybe?
You'll need to restore the 08400001.dat attribute from a backup, or make a new one up by modifying an existing file with a new (unicode) name.
