We have an inhouse app written in Delphi which connects to a local server
running SQL7. When we migrated the database to a server running SQL2000 we
ran into problems.
When a user uses the Delphi app to browse data, it seems ok, but when the
user insert records, the app responded "Connection failure".
In the application log of the event viewer, we noticed the following:
Error: 17805, Severity: 20, State: 3
Invalid buffer received from client.
I did a search on support.microsoft.com for this message. It seems there is
some information regarding this on some complicated cause which will be
addressed in service pack 4.
I wonder should I wait for service pack 4 to solve it, or is there something
I can do?LL

The message indicates a protocol error in the dialog between client and
server. There are several possible causes for this. The most likely
causes are 1) network problems 2) bug in the client library.

only happens when we use a user account to insert/change data via the app.
The only thing that i can say is that the sql 2000 database resides on the
domain controller server, whereas, before the sql 7 database resides on a
workgroup server. i will need to follow up with the programmer to see if
there exist some hardcoded machine name inside the app that causes the
failure.
As for 'bug in client library', i dont know why a failure only happens
during write. but it sounds like i can only try to get the programmer to
check the app or see if there are other compatible versions of delphi that
works with sql2000.
thanks for your reply anyways...
