How was the load on the server? How many sessions could you use of Autocad on a single server? I had always thought Autocad would over work a server if you had more then a couple of sessions running at a time.

Hi, One of my education customers had to get AutoCAD 2006 working in a multi-user environment. While the installation of AutoCAD 2006 was reasonably straight forward, there were 2 issues that were kind of challenging. The first was that only administrators could run AutoCAD in an ICA or RDP session, whereas anyone could run it on the console. The second was that only 2 instances of acad.exe would run. Filemon and regmon didn't tell us anything, and the breakthrough came when my customer's systems engineer, Peter See, turned on auditting and found some privilege violations for autocad running in a TS session. He then found a Microsoft Technote (KB821546) which explained the differences in privilege levels between a TS session and a console session. Once the appropriate privileges were assigned to authenticated users, it was a reasonably straightforward matter to sort out other file/registry issues. An unmanaged policy template took care of almost everything else. Multiple instances of Autocad can be launched provided a bit of scripting is used to make sure each instance of autocad uses a unique executable name, and to suppress a rename error on execution. We've run up to 12 instances of non-admin AutoCAD 2006 on a server so it appears to be properly multiuser ;-) Peter has written up the full installation/configuration process and has made it available to me for public distribution. If people are interested and someone is able to host the documentation, I could upload it for general consumption. One thing this exercise taught me is to take more notice of the information that process explorer gives you, because when I was checking out acad.exe to get around the 2 instances limit, I noticed that the security tab for the executable actually listed the privileges used. Doh... Anyway, I can now state categorically that AutoCAD 2006 will run on Citrix. regards, Rick Ulrich Mack Volante Systems ######################################################################## ############# This e-mail, including all attachments, may be confidential or privileged.
