SDM hanging

I'm having trouble with the SDM on my Netweaver machine. I can log in to it fine...the SDM accepts the password. Along the bottom of the SDM GUI, it says that I'm connected to the server, and that it is attempting to log in. However, it never logs in, nor does it time out.

I haven't found any errors in the log files, but I'll post the relevent information here. Does anyone have an idea about what I can do to fix this? Thanks in advance!
