I'm having a weird problem on two Windows 2008 VMs (inside HyperV) running NLB. They were working at one point, but now TCP/IP appears to be corrupt. I cannot ping anything if logged in with my Domain Admin account:
>ping 10.1.1.1 Unable to contact IP driver, error code 5,
I tried resetting winsock and ip with netsh. That makes no difference:
netsh int ip reset Resetting Echo Request, failed. Access is denied.
I uninstalled NLB, I removed the synthetic NIC and added a legacy NIC from Hyper-V -- no dice.
The weird thing is that it works if I login with the built-in Administrator account, but not my Domain Admins account. UAC is disabled, so this should just work.
Any ideas apart before I call PSS?
Edit: Can't ping anything if I don't login with the built-in Administrator account. (UAC on or off makes no different.) Can't ping 127.0.0.1 (access denied). NICs are the HyperV ones.
I installed SP2 for Windows 2008, no change.
