Hello,

yes, I run Windows 2008 Server R2 without this kind of issues. Maybe a problem with your NIC, R2 has other drivers than "R1" (like Windows 7 / Vista)?? Check another NIC (Intel ...) or a new R2 driver from Broadcom. Or do you use the onboard NIC driver from Windows?

You should also post your question on MS TechNet board: >> http://social.technet.microsoft.com/.../windowsserver

It seems not to be a specific DSS/open-e problem ...

BTW: It's great that more and more Windows 2008/Hyper-V users are coming to open-e - if there are more requests, open-e should put there focus more on MS community's needs!
