Hi !

I have a very serious issue.

It all started from a full Win98 network. On one computer we had a
server program used internally in the company. The server program uses
Firebird 796 for data backend that runs on the same machine as the
server program.

After we upgraded 2 PCs to Win XP (one of which is the machine we are
running the server and database on), the server (database) is only
accessible from the XP PCs, the 98 Pcs on which our client program runs
refuse to connect to the database, no matter how we specify the
connection string: 192.168.0.5:Path or ComputerName:Path. Also, ping
works as normal, file sharing is there, etc.. From the 98 machines I
can't even connect to the database via IB Console. IT gives the error:
"Cannot establish a connection. Unknown Win32 error 10049". If I try to
connect to the database server via NETBEUI, I get a "Cannot attach to
password database". The database is sane, and from the two XP PCs
everything works fine.



Fact is , I can see the network from any PC, but the 98 stations cannot
connect to the server's IP.
Everything has remained the same, the workgroup, the IPs, etc.....

Only TCP seems to be out of whack.
Oh, and I tried something esle. I can telnet in from a 98 workstation to
any of the two XP machines.

What's the problem here? Please give me a hint , as this is a rather
mission critical system we're running !


Thanks a lot in advance !
