    Problem with SMB Scanning on Mac

    Hi,

    I had a weird problem last week, and I'd like to share what I found - maybe it will help some folks out!

    Without going through the seemingly endless tricks and traps on Mac SMB scanning, I had an issue where only one out of 3 Mac OS 10.5 and 10.6 workstations could not be "scanned to". I was working with a Ricoh MP C2550, but that's probably immaterial.

    When configured correctly, you should be able to browse to all of your Mac SMB shares; this one would not show up. Typing the hostname in on the control panel didn't work, either.

    I was able to use the IP address, though, and it worked. The customer has all fixed IPs for their small contingent of macs, so this was more than acceptable, but I still asked "Why?".

    The hostname of the troublesome Mac looked long to me, so I counted the characters - there were 16. Specs for SMB for Windows actually allow for 16, but supposedly one character is reserved, and hidden.

    Turns out that the one extra character was the problem.

    I looked in the TSC Web knowledge base, and some other Ricoh resources, and could find no mention of any limitation anywhere, but obviously there must be one.

    I guess it's safe to say that the limit is 15 characters.

    Man! I never would've thought to check that. I mean, unless it was something StevensPCsoNoonehackit or something like. Ok, maybe 123hasdoin344985y3... you get the idea.

    Your post got me to thinking though. I had a Savin 2828 today that did the same thing. Even after enter the hostname and pressing browse, it would not find anything. Hell, not even the workgroups. I entered "IP/scans" and then the log in screen popped up. Yeah, DNS was entered and connected successfully.

    Again... great catch on the MAC's though! Great job!!
