Hi Tao,
I've encountered precisely the same problem with Netview 5.0 and Framework
3.6
I thought that I've missed something during the installation, however your
information proves otherwise.
It seems that it's a common issue with Netview 5.0 and Framework 3.6 on AIX
4.x (I've tried v4.1.5 and 4.3.2)
I wonder whether there is any way to avoid this problem without installing
Netview 5.1

Regards, Yury

PS. I thank you everyone who was helping me with this matter. Unfortunately
the problem remains...
