I had similar issues but were being caused by "enablesecuritysignature" in the registry on the 2000 server (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters). I have to set this key to 0 in order for network traffic between XP pro and 2000 server to be fast. If "enablesecuritysignature" is set to 1, then XP to 2000 Server is *very* slow. Reference: http://support.microsoft.com/default.aspx?scid=kb;en-us;321169 We also use AutoCAD, Office, etc... Might not be what you're having issues with, but it might help... -Ethan -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx]On Behalf Of Tim Mangan Sent: Tuesday, August 17, 2004 2:36 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: Machines running slow. With TaskManager you can look at a snapshot of memory used on the performance tab. Windows will always keep some free "Available" memory on hand - so if you are using more than, say, 450MB out of the 512 you may be paging. To look at the paging activity, you want to use the performance monitor (control panel->Administrator tools).

I know that this is going to be a silly question, but how can I check to see how much paging is going on? Should I use the CPU monitor on the task manager? Two of the machines don't have Autocad and only run Voloview to view/print drawings. What do you think should be the minimum amount of Ram for those running AutoCAD? Thanks for the reply.

I would look at the memory usage. AutoCAD can eat up a lot of memory. If memory is tight, there should be a fair amount of paging going on.

This may not be an appropriate question for a Windows 2000 group, but here it goes. We have 4 machines in one of our departments in our Seattle store that are experiencing computer slowdowns. At first I thought that it was network issue replacing an older hub with a switch. Then they told me that all of their applications including those local to their machine(like Word and Excel) are slow. I then went up to the store and looked for viruses and spyware cr@p, but nothing out of the ordinary. No rogue processes or other various issues. All the machines are different with 1 being a Dell and 3 being custom built at different times. The only thing that I can see that is common to all of the machines is MSN Instant messaging, XP Pro, Office XP or 2003 and Autodesk Software. They each have 256 - 512 MB of Ram and connect to a Windows 2000 server for other various corporate applications. Any ideas would greatly be appreciated. Daryl S.
