I downloaded process monitor and setup the filters you specified.
Doing nothing I saw thousands of acad.exe "name not found" results in a few seconds.Most of them have the path: C:\Windows\CSC\v2.0.6\namespace\PSDCFP-SM
That doesn't seem right. Is autocad just bagging its head against a wall over and over? Oh wait, that's me everytime I get the grayed out scren and blue wheel of death.
Isn't it amazing.
I did another test and opened Civil 3D 2013, opened a drawing and my test was to just capture what Autocad looks for when just moving a line. I have attached an excel file showing all the files and locations it looks for a file just to move a single line and that is it, I couldn't believe it.
So basically and this is just my guess but every command you do in Autocad it's wasting it's time looking for files, so just imagine when I have 80 users working over a WAN on files and all of our Autocad standards and every single command X 80 going across our WAN wasting time and bandwidth.
I tried a google search for C:\Windows\CSC\v2.0.6\namespace\ and found several links describing a Windows issue with Sync Partnership. Might be a solution in there somewhere.

This all seems pretty serious, it would be good if someone from Autodesk could post a response.
In a way I'm glad that other people are able to see this problem and in my opinion this is a big issue.
The problem is that Autocad does look for multiple files everytime you do a command and it's looking in places that you wouldn't think it would be looking for them and Autocad will try to look all over for these files trying to find them.
There is nothing you can do because this is coded into acad.exe so even though you might just have 1 reference location for example all of your companies fonts on the network, Autocad just sees this as another folder to look through when it's looking for a *.dll, *.arx, *.cuix, etc... so the more folders you have in your profile for network standards the more folders that are added on for Autocad to wastes it time looking for program files that it should be looking only in one location.
One thing you can do however to speed up Autocad is if you do have all of your companies standard fonts, ctb's, pc3's, etc.. on the network is to reduce the number of fonts and ctb's that are in those folders. You can do a test and just have a few font's and ctb's and starting a Mtext and plotting will be faster at least in bring up the dialog boxes.
It's been suggested to us, that you avoid network search paths if at all possible and use robocopy or some other function to localize your normal LAN and WAN Standards....
Here is the response I have gotten from Autodesk on this issue:
Thank you for your patience. The issue where the application is continually reaching over the WAN to look for files in their customized Support Files Search Paths is reported. This causes program to perform slowly. Every time a command is invoked that requires one of the files from the Support File Search Paths, the application looks for it. Not just the once, but every time. Your customer is pointing AutoCAD to continuously access some custom folders and files which are on the WAN network.
Unfortunately, there is no way to keep AutoCAD from doing that kind of searching because it is hard-coded that way.
Being Windows certified program, AutoCAD would respect all the Windows profile related paths, hence it is recommended to keep the paths within the profile (default settings in the deployment). Unfortunately we cannot alter the Programs behavior to suit your environment, but we can make some recommendation.
Use Default User profile for storing the support/custom files, keep these paths locally and that may help with WAN issue.
User profile could be on the server (Roaming), but it shouldnt be setup like a folder redirection.
o If roaming user profile is setup as per MS documents, it will only write back roaming part of the server on log off, and local profile always remain on the local machine. WAN is not used when using the programs.
I think that he means the LAN not the WAN, the only way it'll search over the WAN is if you HAVE ONE with say a VPN tunnel and drives mapped to such... there is a very specific procedure that the program uses to allocate files in the search paths.
It works from top to bottom, so the 1st rule of thumb is to always keep the default folders on your local C drive so it can find the defaults there and keep them at the top of the list.
2nd rule, limit the amount of LAN stored search paths, i.e. extra fonts, extra hatches, extra plot styles, extra lisp routines, extra whatever... now granted you can only have 1 printer path....
3rd rule, don't map drives over a vpn tunnel
remember, cad can copy the profile from a deployment down to the users workstation and they can keep their profile on their c drive, you can over write company wide with some server tools....
the only stuff you want on the server, is the stuff you change all the time that you don't want people to change without sharing :0
with that said, I need to get our fonts and hatches and all that distributed locally and get rid of as many LAN paths as possible, probably just plot styles, plotter, and pmp file
