No server available at the address you entered – hell

I updated to 10.4.7 along with the security updates recently for tiger server and upon returning to the office yesterday I cannot access my locally installed server or manage shares via workgroup manager. When trying to connect to my local server I get the message No server available at the address you entered... and it prompts me to keep it in the list or remove it. I can however connect to an xserve 10.4.7 in the server room via this same workstation using the same server admin app. I tried updating the server apps, copying a new example of servermgr from the xserve's install, deleting my keychains for server admin, and adding SERVERMANAGERSERVER=-YES- to my hostconfig file. none of these fixed my problems. I've found a few threads on the apple discussion boards regarding this same problem, but no real solution. ugh
