With all the glowing reviews I must be doing something wrong; however...
SMB with my Win2K server had been sort of flaky for me before (especially when waking from sleep) but it did work. I could click 'Connect...' in Finder under the Network browser, it would prompt me for username and password (which it would never save to the keychain even if I clicked the box), and I'd be connected. Now I go through that same sequence, same username and password, and I get:
The alias "<servername>" could not be opened, because the original item could not be found.
My server is listed right there in the finder ... how could it not be found?
If I do Go/Connect to Server, I type in smb://10.0.0.39, then enter my username and password, and get:
The Finder cannot complete the operation because some data in "smb://10.0.0.39" could not be read or written. (Error code -36).
Again, something must be wrong in my settings or my methods, but at this point it's hard not to say that I'm worse off SMB-wise with 10.3.3 than I was with 10.3.2. At this point, I'm dead in the water.
