FMS-XPSP2 and Host unavailable

[mcdermottmarian]

I set up a FMS 5.5 database and started the service on an XP sp2 "server". When I move to a FMP 5.5 client workstation, I cannot see the service in the Open: Hosts list. When I type in the IP address (static address) of the server, the FMP workstation still cannot find the host/server. The problem occurs every time I attemp (so our problem is not random unlike reports by other posters). When I ping the server from the same workstation, all packets are sent/received fine.

We have no remote or web clients but we do have a wireless network.

I saw some posts about blocking ICMP messages from reaching the server running FMS. Can anyone confirm if this solves the problem and, if so, can they be blocked at routers and/or firewalls? Another option I saw on posts was to block UDP. Has anyone tried this? Or is there a patch for XP that would help? We are not running server 2003, only xp pro.

Thanks!
