[solved] Vista can't find server anymore

[Philippart]

I run a server (windows server 2003) connected via LAN to my router, till yesterday I could access to the shared files of the server with my Vista Ultimate x64 (connected to the same router via WLAN). Today the server didn't show up in "Network".
I tried to restart Vista, reconnect to the router, restarted the server, even did a Vista system restor, but it still can't find it.
My second Vista Ultimate x64 computer (also connected to the router mentioned above via WLAN too) still sees the server in "Network" and can access the shared folders.

what went wrong? how can i solve this problem?
