I have random domain accounts getting intermittent 530 Home Directory Inaccessible errors when attempting to login to an ftp site. The configuration of the site is listed below.
Configuration:
2 Hyper-V Windows Server 2008 R2 VMs.
1 IIS 7.0 FTP site on both servers.
FTP sites are Hardware-load balanced via BIG-IP F5 on Port 21
Basic Authentication enabled, default domain specified
Allow Rules have been created for the accounts in question, <domain>/<account> with read/write access.
Sometimes the accounts will work, and sometimes they will not.
