When I open a database that uses a custom UDF, I get "ISC ERROR CODE:
335544831 Access to UDF library XXX.dll is denied by server administrator"

It works fine in Windows XP, but now I have installed the FB 1.5 and
my UDF dll under Windows 2000 Server.

I have revised that the XXX.dll exists, I have rebooted the machine,
file privileges are ok

Somebody can give me a clue or what to check please?


Thank you
