After installing Windows 2008 R2 inside VMware, I changed the network driver from E1000 to VMNET3. No problem, Windows 2008 R2 recognized the new adapters after a reboot. I only had to change the DHCP IP address to fixed IP. And then the problems started: apparently Windows 2008 (or Windows 7) won’t let you change the network location as soon as it has put the network in the ‘Unidentified network’ category. Trying ‘to fix’ this problem using the Windows ‘Diagnose’ tool just removed the fixed IP address and put it back on DHCP (and strangely, now the network category is Public).
This, of course, sucks.
However, this little trick should work:
1. Start –> run –> MMC –> press enter
2. In MMC console , from menu file select Add/Remove Snap-in
3. Select Group Policy Object editor –> Press Add –> select Local computer –> press OK –>press OK
4. Open Computer configration –>Windows Settings –>Security Settings –>select Network list manager policies
5. Double click –>Unidentified networks
Then you can select the option to consider the Unidentified networks as private.
This worked for me !
