The very first problem I encountered was that I couldn’t see any of the network shares that I used to see on my old XP machine. After a lot of searching, it seems that Microsoft have beefed up the network file sharing security, and made Vista incompatible with old file sharing system security features by default.
There is a registry hack to re-enable this old mode (Using regedit to set the LMcompatibilityLevel to 1).
I have since found that my PC is very slow copying files on the network - to copy 400 files, totalling just 1Mb from a zipfile onto a network drive took 50 (yes Five Zero) minutes.
The real solution is to upgrade the server software at the other end to be compatible. I’m running samba on a Freecom Network Storage Box (FSG3), and upgrading to the latest firmware, which includes samba version 3, has allowed these shares to be seen again.
This may not be the end - at the moment, the machine seems to be running OK.
There is a hotfix available from Microsoft (Knowledge Base Article 931770 - The copy process may stop responding when you try to copy files from a server on a network to a Windows Vista-based computer), but I’ve not applied it at the moment….
