HI all
I am running server 2003 ent edition domain, with XP prof clients. On my domain I have a problem viewing some websites example:
http://www.colorado.edu/physics/2000/index.pl
Clients can see only blank windows in some ares of the page in which 'Java Applets' suppose to run: If I right click over those areas I copied the errors as:
Java(TM) Plug-in: Version 1.4.2
