Re: Fast User Switching

Hi DrB323,

Two options that I can think of:

1. Alter the "AllowMultipleTSSessions" value directly in the registry, and
don't use the User Accounts applet.

2. See if there are any service failures (checking the Security event log)

When I first logged in, I opened START/RUN/SERVICES.MSC. Both Fast User
Switching Compatibility and Terminal Services had a startup type of
Automatic. However, whereas Terminal Services had a status of STARTED,
Fast User Switching Compatibilty was blank. I went ahead and STARTED
FUS.

I then went into the Control Panel, etc and "checked" the FUS box.

Next, I ran the Regmon (cool tool - soooo much goes on behind the
scenes) and saw where AllowMultipleTSSessions started out a '0',
switched to a '1' (via a SetValue request), and then switched back to a
'0'. However, it doesn't say what or how it's changed. Here is a
screen print of the value going from 0x1 to 0x0:

40.28779221 winlogon.exe:1824 QueryValue HKLM\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\AllowMultipleTSSessions SUCCESS 0x1


40.28846359 winlogon.exe:1824 SetValue HKLM\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\AllowMultipleTSSessions SUCCESS 0x0


Is another service involved that is actually moving or changing the
value back to '0'? The 2 lines above are back-to-back successive
processes. (I had a filter on for AllowMultipleTSSessions and
FastUserSwitching.)

Also, is the Remote Procedure Call (RPC) service involved? This
service was STARTED / AUTOMATIC, but another service called RPC Locator
was (blank) / AUTOMATIC.

When I was reviewing the status' while in SERVICES.MSC, I
double-clicked on each FUS and TS service. There are 4 tabs (general /
log on / recovery / dependencies). Would there be something in there
that I need to check?

As far as auditing, I set that up, turned on FUS, (tried to) switch
users, saw that FUS was again unchecked and finally reviewed the event
log. At this point, I didn't see anything that told me where
AllowMultipleTSSessions was changing. What should I be looking for? I
saw the Image File Name and all of the Accesses, but nothing in regards
to FUS or AllowMultipleTSSessions.

Thanks......
