[nps123]

I have at present windows 2011 server I have upgraded my sage 2015 account to sage 2015 now I can not log on to my sage folders on the office server I have read on sage forums that sbs don't work with upgrade of sage 2015 I don't know what to do perhaps a new server?

Check with the vendor if it runs on Windows Server 2012 R2.
