excel does not open file in network
 

Hello,

I have several computers with XP Prof in a network, one of those is working
as out server.
All of a sudden I can not open office files from this computer, other files
are not a problem, when I want to open a file on another network computer
placed on the "server" it comes a small screen as if it is downloading the
file, and after that comes a screen say's or route to file is wrong or file
is in use.

opening those files on the "server" is not a problem.

Somebody has an idea how to resolve this problem
