FYI, AFAIK, we have not seen this issue occur on OS X Server, using the same versions of FMSA.
I am using Windows Server 2003 with windows xp clients and do not see this issue.
Using FMP 10, FMP 10adv, FMP 10 server.
Thank you for your post, and I apologize for the late reply.
I am unable to reproduce this problem with Microsoft Windows Server 2003. All the clients (including a Dell Dimension with Windows XP SP3) received messages.
Looking through old cases, I could only find one instance of this happening in Server 8, and it was fixed with Server 8.0v4.
Do you have another Server you can try? Would it be possible to set up another machine with FileMaker Server (9 or 10) and try this again? If not, any other information you can provide may be helpful in determining possible causes.
Thanks for your reply.
I'm not able to reproduce it at another customer.
The only difference between the two, is that all users on the affected server are authenticated via External Authentication. Later this month all users will be upgraded to FileMaker Pro 10 and then I will test this again.
At the moment I'm not able to setup another server at the customers network.
Since we updated all clients to FileMaker Pro 10, we don't have the issue anymore.
