[BlueOnyx:17303] Re: Any ideas why...

[webmaster]

I have to run out for a bit and will get back to this but wanted to plop 
this out there before I left


No rhyme or reason why one machine is 64 and one 32
Self taught server guy here (with an agriculture degree)

At the time the first BX OS to WORK on that machine got installed.

Looks like once I get my bad memory issue solved I need to learn a bit 
more bout 64 vs 32 and do some planning

Also since I one have two machines most times I am doing things in 
crisis mode and not thinking things out.  Basically get it back up so 
the clients stop calling

Thanks for the replies
