Strange behaviour of offline folders in Vista Business.

Hi,

I am running Vista Business at home and connect to work using VPN. My home
directory is served by a Snap 520 network attached storage using Samba. This
NAS server is located at work. I made the home directory (about 36GB in size)
available offline in Vista. I renamed one of the subdirectories within that
directory (DERIV_DE was its original name) while I was online and things
seemed to be fine. Then I went offline and online a couple of times and
suddenly a folder with a weird name (EE2LV2~L) showed up among the
directories within the offline folder. EE2LV2~L folder does not exist in the
NAS server. If I traverse this folder I see the following structure

EE2LV2~K\IB6NZ9~A\TUY5V2~X\DERIV_DE

But I cannot access DERIV_DE; I get the "DERIV_DE is not accessible"
message. What is going on? It appears that Vista is creating ghost folders on
the client machine before it sends them to the server, and when the
connection is severed these folders just sit around in the client.

I had a similar problem in the past, and when I deleted the folder with the
strange name it ended up deleting the "good" folder...

Can someone help me with this issue?

Thank you in advance,

Gonzalo
