I have a Synology NAS to store all my VMs on and I am trying to connect them to a Hyper-V 2012 R2 instance (just so I don’t have to convert all of my machines from VHD to VMDK, which would be the case if I used VMware). I’m using a straight SMB share on the Synology to connect up. I managed to get the machines to import into the Hyper-V Manager by actually “joining” the Synology to the domain and adding Domain Computers to the share with the VMs in, but every time I try and turn one on, I get this error [cid:image001.png@01D28DCE.32468EF0] Is this just a failing of the Synology? I have no such problems if I move the VMs to a file share on a Windows server, but I simply don’t have the capacity available there that we do on the Synology unit. Any advice greatly appreciated… [cid:image001.png@01D21FCA.D5DD9850] [cid:image002.jpg@01D21FCA.D5DD9850] [cid:image004.jpg@01D28DCE.32468EF0] James Rankin CTA ACA EUC Solutions Architect Howell Technology Group Office: 0191 4813446<tel:0191%204813446> Mobile: 07809 668579<tel:07809%20668579> Email: ja...@htguk.com<mailto:ja...@htguk.com> www.htguk.com<http://www.htguk.com/> | Twitter<https://twitter.com/htguk> | Linkedin<https://www.linkedin.com/in/markhtg> | Facebook<https://www.facebook.com/HTGUK> COMPANY INFORMATION Howell Technology Group Ltd is a limited company registered in England with registered number 5520670<tel:5520670> and VAT registered number GB 862 666 004<tel:862%20666%20004>.
