Nimbostratuswhere/how does the virtual server hostname show up on the BIGIP
when I do a ping to the virtual server IP, how should it show up? should it show up as whatever I called the virtual server in the virtual server list name (IE if I called it BOB is that how it would show up when I try to ping it)? How does it display itself. I ask because of this. I called it BOB (as an example) but my ping shows sql02 even though the PING goes to the correct IP address. How should that be showing up?

A ping doesn't usually imply any sort of name resolution. Are you pinging from some utility other than the pure ping at the command line? Might you also have some reverse DNS record somewhere that points this IP address to sql02? Here's what a typical command line ping might look like:
PING 10.80.0.65 (10.80.0.65) 56(84) bytes of data. 64 bytes from 10.80.0.65: icmp_seq=1 ttl=255 time=0.085 ms 64 bytes from 10.80.0.65: icmp_seq=2 ttl=255 time=1.00 ms 64 bytes from 10.80.0.65: icmp_seq=3 ttl=255 time=1.51 ms 64 bytes from 10.80.0.65: icmp_seq=4 ttl=255 time=1.50 ms 64 bytes from 10.80.0.65: icmp_seq=5 ttl=255 time=1.02 ms - Kevin_Stewart
Yes I'm just using the pure windows ping. So it seems inconsequential. So does the VM just present itself by its IP? I just don't understand how the BIGIP fits into the windows network as far as name resolution goes.
At its core, a virtual server is represented by a destination IP and port (layer 4). Anything at higher levels (layer SSL, layer 7 HTTP) is managed inside the proxy. Any name resolution would be handled just like any other network device, with either DNS or Hosts entries.
so how does a VM on the BIGIP handle authentication? Is there a doc or does it use windows?
That's a very big and very complex question. There are literally innumerable ways to do authentication with BIG-IP. I'd recommend you begin by reading the quick start guide for the Access Policy Manager (APM) module.

It would most definitely be a host-based VM. Network VMs are generally used for some form of forwarding. This value, the "listener" IP (and port) goes in the destination block. The Source field is for limiting who can access the VM. Any range of addresses that you dole out would be a property of the PPTP service.
