I can install Remote Agent to Workgroup server but can't see it in the console to do jobs

I had this working a while back and I was able to use the SQL etc. backup like for a normal server in the domain. It is not working now. This is a seperate server not on the domain. I can do user defined and see the c drive etc. but not the normal SQL database files in the selection list. I cannot browse to it through the normal resource selection process. This is 2010 R3. I was able to reinstall the agent from the BE console and it knew it needed 2 updates.

thanks for any help
