I have 3 computers set up as a workgroup. No problem there.
I also have a company laptop that is used for VPN into the company's servers. It is set up in the usual corporate manner with a domain. If I select a mapped drive from AS (while not in VPN mode) it asks me for a computer / password as one would expect. But after trying to make the connection I get an error message with a caption of "Network Error" and with a description of: "(1311) There are currently no logon servers available to service the logon request."
This is a new problem with 2.52. I have to use Windows Explorer which connects the drive as expected after logging on.
AS then respects that connection. Both computers are WinXP.
Network SignOn Error
