mr asp.net account doesn't like his home

so here's something funky, the asp.net account in the wwwroot folder has disappeared off this one server a couple of times.

and it's getting real annoying to go to pages and get that annoying error message.

i checked the event logs for a 630 of asp.net but couldn't find anything. I've written this off as being a ghost server (well not an actual ghost server but a server that is possessed by a ghost).

has anyone else experienced this magic known as frustration to me? I'm seriously going to drop kick this server if it keeps pulling this crap....
