We upgraded our ESXi 5.1 to 5.5 U2 now a Windows 2008 R2 VM has no NIC driver installed.
We've checked under C:\program files\vmware tools\driver to find it for re-install but it's not there.
We also checked under c:\program files\common files\vmware tools\driver.
We upgraded the Virtual hardware of the VM from 8 to 9 (if we went to 10 I believe we can no longer use the VSphere client to manage the VM's and have to use a web interface?) using the CLI command.
Q - Do we need to upgrade the virtual HW to v10 for the NIC to start working, we have other working VM's running v9 on this host.
Vm was removed from the inventory list and re-added.
We have tried to install the latest VMWare Tools but it just sits at installing for hours. Same result if we try and remove the current VMWare Tools. Odd thing is the server is responsing quickly when navigating and opening programs etc.
