False Read Only

Along with many others, we are experiencing sporatic problems with drawings
changing to read-only in mid drawing session. The only work around seems to
be saving the drawing as a different name and then exit AutoCad and
overwrite the original.
This technical document implies a possible solution:

It says that the 3dUpdate may fix the problem. It is true that I do not
have the 3dupdate installed. I'm wondering if anyone has any experience
with this solution? Or any other options?

Has there been any progress on discovering the cause to drawings randomly
changing to read-only? AutoCad will allow a user to open a drawing and work
in it for a while, then without warning it will be flagged as read-only. It
is a very annoying problem to have to SAVEAS and then exit AutoCad then
re-enter and SAVEAS again. Not only that but once the drawing becomes
read-only for the user who has had it opened, it is free to be opened by
anyone else. This can be very, very awkward.
I'm using WinNT 4.0 both servers and workstations and AutoCad2000 sp2 with
the 3dupdate also. In my office the victims have been using a variety of
video cards (all with the latest drivers). Most of us share the same NIC,
but not all have experienced the problem, so it seems the NIC is not the
culprit. I've had users that have experienced the problem in the past and
received a completely new PC, only to have it re-occur. We've had the
network checked by an outside consultant and there is no reason to suspect
anything on that end. I've read a report in this newsgroup of an instance
where the computer was disconnected from the network. I've heard the line
about "It's the operating system's responsibility to control file locking"
and that is not good enough. No other software has this problem. I also
know that many flavors of Autodesk products share this problem. So it's
pretty obvious who's responsibility it is to fix it.
I'm contemplating an upgrade to ADT3 that is going to cost over $60,000.
But to shell out that kind of cash and still have to deal with this issue
that has been present since day1 is going to be hard to justify.

Any help or compassion is appreciated,

Hi Michael,

If you look at my previous postings, I have addressed the Read-Only problem
on this forum numerous times. Random Read-Only problems are generally an
indication of a network performance issue. This can be a busy server,
packet loss or delay or perhaps a server that is significantly slower than
the workstations. Essentially, what happens is that an AutoCAD API call to
release a file lock gets dropped or processed too slowly, allowing AutoCAD's
API call to manipulate the file to reach the file in locked status. It
takes packet level diagnostics to detect this. The reason why other
applications are not doing this to you is that AutoCAD, by nature of its
complexity of file manipulations, makes API calls that are not used in a lot
of other applications.

It may help to log each occurrence, you may be able to detect a pattern such
as time of day, physical connection points, number of users active on that
server or specific jobs being run against data stored on the server. I
would also make sure that you have the latest NIC drivers on all of your
systems.

Hi Jerry,

did anyone ever report about this problem with R14 (we never had
problems...), or is it just due to the fact that Autodesk has done incorrect
modifications to the code? Or, is there changes in some (Microsoft?)
libraries or anywhere, that could in near future possibly impact to some
other applications updates?
