{This should probably be in Security" forum...} Windows 7 RC. Applied latest updates June 30. After reboot, my shares (to local Unix SMB shares) wouldn't restore. When I clicked on the mapped share icon in Explorer, I got a popup stating "This account is not authorized to login from this station " I can successfully re-map the shares, so there's nothing wrong with the remote side definitions. The credentials appear to be saved, as they are listed in the list of previous shares when I do the re-map. Searching on that message, I found other forums listing "SMB signing for network clients" as a possible cause. All of those settings are disabled, both in the Control Panel and in the equivalent Registry settings. I created a new admin account, mapped three remote shares, logged off, then logged back on, and got the same result - "can't restore connections" and "account is not authorized to login from this station "... I tried to restore to a point prior to June 30, but my back-up is on one of the Unix mapped shares and Backup can't"see" it anymore. Any ideas?

This sounds like my problem, do you know what update was applied? If I can track this to an update I can unistall teh update and hopefully fix this!

I have the same problem! Have you found any solution?

My problem was fixed after removing a numebr of updates. the one i think caused this is the office live add in. Certainly after removing all office related updates my problem was resolved, I have since reapplied some but not all of the available office updates and am still working. The above update was isolated through trial and error. What is more interesting is how an office update has managed to break a network protocol???????
