vlc server help

So I have this problem:
I have 2 computers. On first one there is vlc server. On the second one I want to play that stream.
Playing stream works on first computer, but on other won't.

Computers are connected directly with utp cable. IP addresses are 192.168.1.100 and 192.168.1.101.
On first computer there is windows 7, and on second windows XP.
Their firewalls are turned off.

I start vlc server with next command line:
vlc -vvv film.avi --sout "#rtp{dst=239.255.100.100,port=5555,mux=ts}" --no-sout-rtp-sap --no-sout-standard-sap --sout-all --sout-keep

On client i start:
rtp://@239.255.100.100:5555

Thanks for help
