Hi Ray,
Seems a bit hit or miss, can't think why.
Permissions thing :
Backup worked fine when I logged onto my machine and SME box was only a workgroup machine but when I switched it over to a PDC the user that I thought had all rights on my Windows box didn't have access to where I wanted to store the backups. I checked over the 'message' log and it wasn't able to mount using smbmount, access denied would show up.
What I did was set the the permissions correctly for the local user and added the domain user with correct permissions on my actual desktop machine and viola, it started working.
I needed to get the backup working at least as I have actually started using this to host my domain and also to manage my small home network.
Still need to get sysmon working now which also seems a bit hit and miss, worked, didn't work, worked and then didn't again. Maybe you could lend a hand here too?
