I'm bumping my head to the wall.

There are two notebooks in front of me. Both with windows XP Pro SP1
(latest hotfixes), NWCL 4.90SP2, NIPP 3.12, Sun Java 1.5.0_01. The same IE
with the same Preferences.

On one system I start http://xxx.xxx.xxx.xxx/welcome/index.html and select
"pinter install" (in german: "Drucker installieren". Then a window pops up
with all the iprint-printer at the server I can install

On the other system it pops up a empty window. The same url but absolutly
nothing in it.

Can anybody help me????? I don't know what I should do else
