Backup Connection Error

Same problem. Everything was working fine, until I changed my main PC to Win 7 Ultimate x32.
- My User Share does not appear in >Network view;
- No other shares (/pub, /Music, etc) appear either;
- ReadyNAS appears as a "Media device"; selecting it starts Windows Media Player;
- ReadyNAS also appears as "Storage"; selecting it starts FrontView admin in web browser.

Meanwhile, all the NAS shares appear as they should on my Macbook Pro running OS X 10.6.7 and on my laptops running Win XP Pro and Win Vista HP....

The FrontView backup "Test Connection" option reports "Error connecting to //MYPC/mysharedfolder". All of the folders to be backed up are shared and can be accessed across the network. I have checked/double-checked my "Backup" user settings and password.

The backups have been failing, and the logs report the "Reason for failure:" as being "Unable to access remote path //MYPC/mysharedfolder".

HOWEVER... I have today discovered that I can access the shares by mapping drives - but this is a work-around and shouldn't be necessary (or should it?).

AND... Now that I have set up a mapped drive, the FrontView backups appear to have started to work (when manually started, at least)!

BUT... The FrontView backup "Test Connection" option STILL reports "Error connecting to //MYPC/mysharedfolder", both before and after a successful (manually-instigated) backup!

Why would this be?

I paste below the last two log entries for my "test" backup. The most recent was manually started, which is presumably why there is no "Backup started" timestamp?:

Any feedback/info would be appreciated. It seems that I have sort of solved my problem, in that by setting up a mapped drive on my PC it seems to have "unlocked" the backups (although the "Test connection" STILL reports a failure) but it's work-rounds, and I don't feel comfortable with it as a robust and reliable solution.

Having made a considerable financial investment in the NVX, I'm disappointed that it is not working more robustly/reliably.

Thanks a lot
