I have an Exchange 2007 in place, the queue is giving me a 421 4.4.2. connection dropped error on some domains I’m sending to, tracing the logs shows the connection is dropped after the BDAT command.
I have found this on the internet:

The reset process is surprisingly simple: hit F9 during the boot process and the reset wizard will start.

Tracing these accounts in the past wasn’t an easy task.
To trace these accounts in the directory the easyest way is to search the computers that have not been logged in to the network in a given time interval. READ MORE »

It seems (after digging the internet) that FreeNAS and ZFS needs 64Bit CPU and at least 4GB of memory to run without crushing and/or panicking (panic: kmem_map too small). READ MORE »
