samba - Mar 2001 - Request for AutoCAD help with Samba server!

Hi everyone,
If you have experience using Samba < 2.0.7 with AutoCAD 2000/2000i or R14 on
a LAN, where the Windows 2000 Professional clients running AutoCAD
2000/2000i are opening .dwg files and XREFS off of the server, particularly
if you know tips on tuning Samba's performance so that AutoCAD reports it
can't find files on the server or load XREFs, please either post your
comments to the list or you can email me off list.  I am administering a
mixed PC/Mac network for an architectural firm, and Samba began to have
problems with AutoCAD about 1.5 months ago. I have no problems with many of
the things that people often report trouble with, encryption of passwords is
working fine, only problems are serious issues with AutoCAD where a user
will find that they do not have read/write access to a file that belongs to
them or their group on the server.  Below is a copy of my smb.conf:


------------------------- /etc/smb.conf ------------------------------------

Hi

We use AutoCAD 14 and 2000i in Win 95/98; Samba 2.0.7 in Sun Ultra Sparc, 
Solaris and in a dual PIII linux server.

Open files from the server works well! But, for secure, I do not recomend. 
It is very easy to users make mistakes, like move a hole directory to an 
unknow place (always happens with explorer), or to have an AutoCAD system 
crash and, as a side efect, delete all files in corrent directory! It happens!

We used to do not open the DWG file direct from the Samba server, insted, 
the user copy the file to the local disc, work on it, and copy back to the 
Samba server. If some thing goes wrong, it goes wrong in local disk, not in 
the server! We use a Control File System to securelly copy from and back to 
the server.

The XRef?s are located in the Samba server but I configured AutoCAD to make 
a copy of it in the AutoCAD temporary files directory (local disk too) when 
it load the XRef?s from de server. AutoCAD locks the XRef?s as they are 
loaded! To configure it: set XLOADCTL to 2 and, I recomend, set INDEXCTL to 3.

I hoppe this can help
