Default Server damages datafiles

I instaled NX 1.03 on a WIN NT server with XP clients using TCP/IP.
The server was installed as a sevice and it started with no problems.

neither the server service nor the server application saves its
configuration data on exit. If I select the save function, data is
written to the config file. If I stop the server application or the
service, the config file is overwritten with blank data and the server
has to be reconfigured when next it is started.

I ran the server as an application and entered the configuration
information, and ran a data conversion utility that reads data from FF
tables and writes it to empty NX tables. After writing, the NX tables
get corrupted. Prior to writing data to the NX tables I can open the
tables with EM. After the write, EM reports corrupetd tables and
cannot open them.

I have done several of these installations/conversions using the same
utility, NX versions and server/workstation combination with
absolutely no problem.

I checked everything that I could think of and could find no prbolems.

When I install the server on one of the XP clients it writes its
config file on exit with no problems.

Is the exact NT version: "Windows NT Server 4.0, Terminal Server Edition"? I
remember that particular NT version gave FF some strange trouble as well in
the file API department.

....winding backwards in time... hm... it might actually have been W2K AS
that I had trouble using FF on.

Anyway, you dont get any error messages raised during these operations, or a
log file from the server with errors?

Could I also get the exact NT version, including service pack level?

No error messages were logged, but it appears that there are some
issues with user permissions. I am working with the client's System
Administrator and believe that we should be able to correct the file
corruption problem once all the correct access rights have been
assigned.

I am not sure that the inability of the server to write the
configuration information is the same problem. I will post the outcome
or a shout for help after the security issues have been cleared up.

Thanks


Tony

Thanks for the update Tony. FWIW i've an item on my schedule for mid next week
to look at how the server does under restricted accounts in winnt+. I know it
works fine as a service but it might be that some of the interactive things
give troubles (select dialogs, file access, ...)

Eivind,

I have several FF and Nexus apps running on NT Terminal Server,(5 years),
and Win2k Citrix servers as services without any problems. They are always
installed with domain admin rights accounts.

Just my two cents worth.

I used to run FF on W2K Advanced Server at home. On that machine FF Server
had a 100% reproduceable problem: Reopening a file (table) on the next
sourceline after closing it would fail (this is what is used to force
buffered writes to the harddrive). The OS needed a Sleep() inserted between
the closing and opening, or it would often fail to reopen the file. This
often happened when starting the FF server, and led to wrecked server tables
etc. It was fixed in FF 2.05 or thereabouts I think. Sean logged on to my
server remotely to fix.

In case you're wondering, NexusDB has a similar safeguard already in place.
