We move our WSS 3.0 site last fall. Since then we have some problems in Central Administration that we have not been able to resolve. The CA site will come up, but there are a number of pages that error out. For example, under operations -->Servers in Farm returns "unknown Error", Timer Job Status retunrs "unknown Error". We have tried a couple of times to find what the error really is and what is causing it. Any suggestions?
