I have two virtual servers that are having the same issue. both are giving me an error starting Microsoft Emulated IDE Controller (Instance ID) failed to power on with error "One or more arguments are invalid", Failed to open attachment c:\location error, one or more arguments are invalid. It does this for the hard drives and network cards. All the other VS devices on this host are fine. Everything is where it should be and all permissions are set.

Hi,
Is c:\location the path to the virtual disk files? If yes, move the virtual disk to another path and change the virtual disk path in the Settings of the virtual machine, then see if the VM can start. If the issue persists, delete the current VM, create a new virtual machine and reattach the virtual disk to it. If the new VM still won't start it could be the virtual disk that is corrupted.

Tried all of that and got the same errors.
I finally got the systems to power up. I ended up having to remove the MRT and RCT files that where in the location. After that the systems where able to boot up.
Glad to hear the problem is solved, please mark the reply as answer.
This post about removing the MRT and RCT is gold! The network I'm responsible went down yesterday afternoon as I have a couple of Cisco Virtual Appliances that were not live migrating. Without live migration I wasn't able to complete Updates on the Two Host Hyper-V Cluster I run.
I was forced to turn off the Virtual Appliances in the hope I could then migrate them, but they then failed to turn back on. Without the Virtual Appliances which most of the DHCP VLAN scopes point to for Web Filtering via Cisco Umbrella. Internet went down for everyone. I had to amend the DHCP scopes to point to the local DNS servers and bypass filtering.
Finding this post and deleted the files above had me back up within minutes (after I'd come across the post that is) there was several hours of downtime whilst I tried to get the VM's working on my own first.
