[THIN] MultiUserEnabled setting on Windows 2003 Terminal Servers

Hi All,

As per KB818528 my customer had enabled the MultiUserEnabled registry value
on their previous Windows 2000 Citrix Servers from there inception many
years ago. At the time this was due to issues with their Samba servers.
This "tweak" was included in their upgrade to Windows 2003 PS4.5 servers,
which is referenced in KB913835. It was not previously baselined, but a
performance audit shows the Redirector/Current Commands reaching over 200
in PerfMon. This is not good from an SMB performance point of view. In all
Terminal Server environments I have deployed over the years I have never
enabled this setting, and typically see the Current Commands sitting at
about 60 on heavily utilised servers, after the standard SMB tuning of
course. I have raised the current value as a concern, but the customer is
suggesting that this may well be due to how the MultiUserEnabled setting
works. There is no evidence anywhere on the Internet that suggests this is
the case. Therefore I am asking if the Current Commands value I am seeing
should be flagged as a serious concern? Does anyone have experience with
this?

I have also ask the same question to the MS Terminal Services and Windows
Server Performance Team's via their blog sites.

Cheers.

 Kind regards,
