a few days ago I installed FB on a PC running W2000 professional, v.
5.00.2195.

Today I tried a backup for the first time.

From the command prompt, I wrote:

\programs\firebird\gbak -b -user SYSDBA -pas masterkey foo.gdb foo.bk

I get the following error messages:

"message length error (encountered 244 expected 246)"

"gds_$ received failed"

"exiting before completion due to errors"

"cannot disconnect database with open transactions (1 active)"

What does it mean ?

What is causing problems ?

In particular, all users were disconnected at the time, so I cannot
understand how a transaction could be open...

Thank you
