Guest can't connect to network after upgrade to R2.

-

i had win 2008 std server running hyper-v, running win 2003, sp2 guest. host upgraded 2008 r2. guest network cannot connect lan, either via dhcp or static ip.

i have removed integration services drivers, removed virtual nic, removed virtual network,re-added virtual network, nic detected, installs,

but cannot dhcp address, nor function static ip.

i seem stuck....

 

 

you covered basic things (the first being upgrade integration components in vm).

frequently find necessary delete , re-create virtual network on hyper-v server.

then change configuration of vm select new virtual network.

you can try vm emulated virtual network adapter, if fails need move stack virtual network.

this can happen number of reasons.

i find when export vm hyper-v v1 , import hyper-v r2 informative message related network stack.  have open settings of hte vm , select virtual network , well.
