Windows Server 2008 R2 loses ability to connect to network share

- by JamesB

I could sure use some help with this one: I've got two Windows Server 2008 R2 x64 Terminal Servers, as well as several 2003 servers (DNS / Wins / AD / DC). On the two 2008 boxes, every now and then they will get in this mode where you can't map a drive to a random server. I say random server because it's not always the same server that you can't…
