Info update,

Vista workstation: deleted Temporary Internet Files + Outlook Security
Temp + User Profile Temp + Windows\Temp - folders files, and after that
started Outlook and tried to save attachment to mapped drive = no help,
still error, and *.tmp - file on server.

Tried to save 4MB and larger files -> always *.tmp - file on the server,
and tmp-file size is same as attachment size.
Tried to save *.pdf - file, and then tried to rename *.tmp - file on the
server to *.pdf, and after that tried to open with Adobe Reader. Reader
just said that the file is corrupt.

Network is 100Mb between workstation and server, ping goes nicely to the
server (ping server.domain.local, so this this ping does DNS resolving).
Monitored network traffic when saving Outlook attachment to the server
-> immediatelly when pressing save-button, the network traffic rices to
about 25%, and then really fast goes down to 0%, then Outlook wait about
30 second, and after all Outlook gives the error, can't save the
attachment. There also goes the infobar, tha Outlook is saving file, but
the bars indicator doesn't move, and stays about 10% place.

Best Regards,
Pitti
