I tried using the Domino Toolkit for WebSphere to connect to both the TLCC and NuTechs servers with DIIOP running on them, and it didn't work. It looked like the connect operation the Toolkit was trying to perform kept timing out. Hmm...seems strange that this would happen with the Toolkit, as I've been able to connect to the TLCC servers using the remote classes in NCSO.jar previously.
