Lotus Notes error message

Possibly some other application on the program has put a lock on the names.nsf file on the machine.

Ensure any scanning software(anti virus) ignores *.nsf files

Is there any applications that try to open an ODBC connection or .com connection Lotus Notes.

What OS is the workstation and is the installation a single user or multi user install.

OS Windows XP
Single user installation.
Virus Scanner: Trend Micro Office Scan

Could it be that the user's installation tries to open a "local" Notes database that is stored in a shared server directory?

To find out what happens, you could add some debug parameters to the notes.ini files.
See

and search for "Use CLIENT_CLOCK to Troubleshoot Database Performance"

I'm guessing the user doesn't have access to certain files.  Check the security of the actual files: notes.ini, names.nsf, etc.  Did you install Lotus Notes with the user's credentials or yours?

Seems a good guess indeed.

You get this error also when there are multiple users sharing the same data directory, either because multiple users log on to the same machine or the data directory is on a network share and already in use.

Each instance of the notes Client needs it's own data directory.

Each client has their own data directory on their local machine. Their mail file is saved on the server.

Any debugging results?

huh, name.nsf is unknown to me.  Please attach a notes.ini

@Lars: as if you don't have any typos in your posts... ;-))

thanks

Was that indeed the answer to your question? Or did you have to close this question and you just accepted the last one??
