I think this problem has already been discussed before on the community. The solution then was to enable Anonymous login on the web server. IIS required some special steps, IIRC.
Please do a community search for the error message you mentioned. If I can find one of these dicussions, I'll post the link.
Thanks for your quick answer.
I did community search and internet searchs before posting (and already found those links but thanks anyway) :-).
- We are not working with IIS.
- I'm not quite sure what are the consequences of enabling anonymous access : All our authorizations on document and directories are user-specific. We need to keep that.
How does it work with licencing then ?
