I don't have any problems with DEP(WinXP SP2 or Win2003 SP1) and FB
1.5.2. If you are using UDFs that write to memory and doesn't do it
the correct way that it would be accepted with DEP, then yes Firebird
will have problems. But, I did notice that with Win2003 SP1, I had to
make sure I was connecting via TCP/IP and not the local protocol(IPC).

What is the actual error message?
Is it an ISC error code or another error code?
