DML caching requires the use of server events. I have heard of events
being a problem with the Firebird Classic server, although there are other
known sources of problems with events. The most notable is the use of a
mismatched gds32.dll on your Windows client. You need to use the client
version that comes with the Windows server kit, build WI-V1.0.0.794.

If you are not using Classic and you do have the correct client version on
both client machines, then post a question in the IBO list with fuller
details of your connection setup.
