Hi there, I've upgraded Server 2008 Ent ed to Datacenter, I managed to activate, and to go on internet but I can't do any updates, both on the host and VM; my FW is off, the host file hasn't been changed. Other PCs can actually access update web site. I usually experience this problem when a VM is not yet activated, but in this case it shows activated. Any idea , please? many thanks Andy

Hi guys, thanks a lot. I tried all of the above solutions, the one that actually sorted out my issue is actually :http://blog.ronnypot.nl/?p=310 , infact disabling the Large sending offload setting under network adapter solved my problem. Reason why it was working before and suddenly has stopped working, I guess, it's because I 've changed the adsl provider, and therefore the router: probably different settings in the router. Anyway, this was my case, other people may find a solution from the other links you suggested, I think it's good to have them on the same page. Thanks
