I recently had to upgrade samba to 3.0.14a on my fc3 box because of authentication problems with Windows Server 2003 SP2.

Authentication now works perfectly as does printing. Unfortunately, any time I try to create a file in a samba share from a windows machine, I get a 'specified network name is no longer available error.' In the log files on the samba server I have...

There's been no change at all to my smb.conf.

Anybody have any ideas where I might start to work this out?

This question rings a faint bell -- I think the answer is somewhere at samba.org, but where? I tried a google on:
"specified network name is no longer available error"

You can find links to 2 official Samba texts here.

If I have seen the answer, it's probably in the 1st 3 ch. of the 2nd book.

Well, I'm glad someone else has even heard of this!!! I've found nothing on Google so far, but thanks for the tip. I'll hunt a little harder in the depths of samba.org
