CIFS Release Notes (769570-001, March 2014)

Issue
When you use terminal server clients to access to shares on a CIFS server, all of the clients from
that terminal server connect over a single virtual connection and are serviced by a single SMBD
process on the CIFS server. These actions might lead to a number of issues, including too many
files open by a process, too many locks, and performance degradation for the clients, since the
clients share a single SMBD process.
Workaround
For the Windows NT, you can set a registry parameter, MultipleUsersOnConnection , to 1,
which forces each terminal server client to negotiate its own connection, so that each client receives
a separate SMBD process. For the Windows 2000 terminal services, Microsoft provides a hotfix,
Q818528. You can apply this hotfix, and then set the following values:
Subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MRxSmb\Parameters
Type:REG_DWORD
Entry: MultiUserEnabled
Value: 1
NOTE: Do not install the Q818528 hotfix on a system running Windows 2003. This hotfix only
applies to Windows 2000.
For more information, see the Microsoft Q818528 article: http://support.microsoft.com/
Issue
The The file may have been changed error message appears when you save an Excel file
to Samba. The error message also provides choices to either save a copy or overwrite
changes.
Workaround
When prompted, select overwrite changes otherwise the file must be saved under a different
name.
To avoid this error, change the registry as described in the Microsoft knowledge base article at
http://support.microsoft.com/default.aspx?kbid=324491
The Samba community also addressed the issue and has further characterized it on the Bugzilla
webpage at https://bugzilla.samba.org/show_bug.cgi?id=1094
Issue
Because of increased Windows security requirements, profile storing might fail if adequate authority
has not been configured for roaming profiles.
Issue
Some Windows 2000/2003 Domain trusts might not be recognized by HP CIFS server, including
some intra/inter-forest trusts.
Workaround
When required to accommodate the intra/inter-forest trusts that HP CIFS member servers might be
exposed to in a forest, shortcut trusts can be explicitly created. HP CIFS PDCs support external
trusts, which can be sufficient for Samba and Windows inter-domain trust relationships. For more
information about Windows 2000/2003 trusts, see the MS TechNet documentation at http://
