Has Microsoft changed anything that could be causing DdeConnect to delay after the startup of the computer?

Our developers have noticed that DdeConnect is causing a 30-second delay (time:ing out), in our software (which has worked for over 10 years without problems). It seems to mostly occur right after starting the computer, where it will time out several times in a row, and later on it gets fast again.


When starting our appliction the DdeConnet makes it delay with 30 minutes eventhough it doens't fail. It wasn't like this before. It worked instantly.
