Never had this before running Ubuntu file-server and DS209+ on DSM2.2.
Now I have it on 2 computers, one Vista NL ACER the other HP Windows7 US, accessing both a remote (via VPN) DS209+ and a local DS1512+ both on DSM 4.0-2228.
Sometimes if I try to save a file I cannot...it just happened after >15min modelling in CAD!
If I try to create a document via filemanager on the server I see it gets created, but I cannot give it a name or it will respond that the directory it is put in does not exist. The I end up with a "new document.txt" or a "new folder" which I then cannot change any more. I can delete it though.
But my CAD system refused to write the open document not even to the local drive when it occurred. That would give rise to think that it is related to Vista!
I'll just tried the above, but still have to reboot....
