performance problems

hi

i'm having problems sharing files off my vista box
on other machines at home, many times applications (explorer, etc) stop
responding when accessing shares on my vista box and occasionaly will say
"the specified network name is no longer available" then will automatically
recover itself

the problem seems to be with the server service on the vista box
anyone have any ideas how to resolve this? i found articles on modifying
some registry values under lanmanserver\parameters, but the articles pertain
to 2000/2003/XP and the values mentioned don't exist in vista so i don't
know what the equivalent would be.

Log Name: System
Source: srv
Date: 7/5/2007 11:14:54 PM
Event ID: 2021
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: <computername>
Description:
The server was unable to allocate a work item 1 times in the last 60
seconds.

just to add, running vista ultimate
and in event viewer, the "event log online help" link is useless as mmc
causes an "unhandled exception" 0x800706AB

Any thoughts anybody? I'm seeing same problem: lost connections,
"delayed write failed", explorer and other apps hanging for 3 or 4
minutes. Look in the event log and there's lots of event 2021. I've seen
"number of times in last 60 seconds" as high as 1100.

I'm running Vista X64 Ultimate on a quad cpu with 8GB of RAM. The root
cause, according to all the microsoft articles, is slow disk i/o but my
7200 RPM SATA 2 HD can hardly be described as underpowered.

One sure way to trigger the 2021 event is to run Visual Studio in a
virtual machine under vmware with all the source files residing on the
Vista host - run a build and there's the 2021 event. I've never seen the
problem when doing same on a WinXP laptop. I had the same problem
(although in a milder form) on an older WinXP desktop though. Perhaps
vmware is a good way to trigger the problem because all that virtual
networking can probably put a lot more strain on the server than a
physical connection - and perhaps the faster the box, the worse the
strain...

There's a few microsoft KB articles with suggested registry tweaks but
I have no confidence that they apply to Vista, let alone Vista x64...
What worries me is not the fact that the registry values mentioned don't
exist on Vista (they don't exist by default on XP or 2003 either), but
rather that there is no indication of what values make sense for Vista
x64.

Any thoughts greatly welcome...
