I have periodically happens such garbage: run a client-server application, it complains that it can not communicate with the server database (ilpi do not start and says that the server is unavailable). Pinguim the server, it says everything is normal. Now again run the application — everything works.

For unknown reasons, this behavior seems somewhat strange

Yes, everywhere there are different WindowsCE (what exactly do not know)

Possible problem with ARP-request/ARP-cache.

I also sometimes see this strange phenomenon in different situations involving data transfer. Call it "procrules"

As an option: perhaps the appeal is the host name and DNS the brake (or, for example, the primary DNS was down, and the secondary works). The application tries to access by name, a DNS query takes too long to respond, the app crashes on timeout. The essence of the case, the DNS request fails (or is sent to the second server), IP address is cached. So the ping is taking place, and the application starts to run.

one of the symptoms of disorders of the DNS. Verify the primary server in the client settings — is he okay? After ping entry goes into the local cache of DNS and why it works.
