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.
