Problems access database files on a Filemaker 9 server from a Mac client

Post

I am running several Filemaker database files on a 9.0 Filemaker server. I have several Macs that access these files using Filemaker 9.0.3 advanced. One iMac running Mac OS 10.5.5 can not see the filemaker database files. The configuration is the same as the other computers. I launch Filemaker advanced 9.0.3 and select remote. I can see the local host server just like all the other computers. However when I click on the host no files show up in the list. They do on all the other computers. Just not this one. I have tried removing the Filemaker application and all preference files and re-installing but it still does not work. Any ideas?
