More experiment - bit like a dog with a bone

Started VM on my Win 7 Prof PC: Win PE runs then Reflect
Clicked on the DOS icon in the task bar and ran ipconfig and nothing is listed.
Closed and edited VM settings and chose Intel Pro 1000MT Desktop (82540EM) adapter.
Restarted VM and went to DOS window and tried ipconfig. Now it lists the ip address of the VM.
I tried arp -a and it lists the ip address of the VM and under that the router IP address.
I went to Reflect and browsed, clicking on the network icon but all that is listed is a RaspberryPi. The host Win 7 and other network devices are not shown.
I then switched on my NAS and now I can see the NAS on the network when browsing.
Back in the DOS window I again ran arp -a and it lists the VM and under that:
- the router IP address
- the NAS IP address
- the Win 7 host IP address
- the Rasp Pi IP address
It does not list my Alarm system or my analogue/SIP adapter but then these are not storage devices.
I then tried browsing to the NAS and successfully logged on and could see all the folders

I selected an image and Reflect loaded it in the Image Restore window.
So. The problem is solved by a different network adapter. Strange as the adapter I used first (PC-Net FAST III (AM79C973) is OK with an Windows XP VM.
I still cannot see the Host PC on the network or find it with a \\<domain name>\<shared folder name>. It says the specified folder does not exist - no login prompt. Maybe that is a Firewall/Security issue in the Host.
I shall mark this as solved.
