Thanks very much to all,
I had saw some comment about the SMBv2 protocol, but not the"Why". I
didn't found relation between SMB protocol and Firebird TCP/IP connection.
This link is very useful for know the cause, but we need waiting for a
windows patch.... or not..
Meanwhile, I installed /Avast/® in some PCs and *all is ok!*, but I
think that is not a final properly solution.
I will install this for a rest of Pc's and luckily all will be like
later. I hope it...
Thanks,
a Reveure

Hi!
We have exact same problem. Author of some previous posts here in this
group (THANK YOU AGAIN!) gave us the asnwer how to solve the problem.
Problem is with update WIN 10, uptd 1803.
https://blog.mertech.com/windows-10-version-1803-breaks-some-shared-folder-applications
*The Version 1803 issue in detail*
It appears that Microsoft has introduced a bug or security feature
that prevents applications started from SMB v1.x network shares from
making network connections. This means that applications started from
these environments can’t open a connection to a database server. In
fact, they can’t perform any other types of network calls either.
This problem most commonly occurs when Windows 10 clients access a
custom application from a mapped drive on Windows Server 2003.
Unfortunately, there doesn’t appear to be a way to upgrade Windows
Server 2003 to use a newer version of the SMB protocol. The only
workaround in this environment is to copy the application executable
to a local disk and run it from there.
-----------
We choose to update our Server 2003 to get newer protocol and for time
beeing we copy each of .exe to local machine. It all is described in
article above (link).
Best regards,
Primoz

*Subject:* [firebird-support] Error -902 after Update Windows 10
Hi
Since few days ago, after Windows 10 update, some applications writes
in Delphi can not connect to network Firebird 2.5.5 server.
These applications can connect with BDE, InterBase, FIB, FireDac...
but all are using the GDS32.dll
In other side, applications as FlameRobin, are using the same library
GDS32.dll and connects successfully.
Clients with previous Windows versions works fine too.
These are the errors messages:
Interbase:
22/05/2018 17:48:03 DBUG: ; ¬[Application: ]¬[Error] -902 335544721
Unable to complete network request to host "192.168.1.100".¬Failed to
establish a connection
BDE:
OpenConfigDatabase DbConnection Exception. Error Opening Configured
Database $AUTO_DATA, Error was: Unknown database.
Unable to complete network request to host "192.168.1.100".
Failed to establish a connection.
The problem is a kind of local issue, because other Pc-clients works
fine. But certainly is the gds32.dll that cannot connect with server
and I not known why.
Some help please?
Tank you.
a Reveure,
