Hi All, I am having a problem with a chat program written using directplay8. It had been running for more than a year without very many problems. A few days ago it stopped working (was not able to connect to the server computer) under a normal user, but is still able to do so under administrator. The normal user is able to ping the server. There are two other computers that are able to connect w/o a problem. All computers, including the server, are running win2ksp4. Any ideas on what could go wrong would be greatly appreciated.
