Accessing an instance on NT Wrkst

I just set up OEM V204 on an NT 4.0 wrkst. I have an 805 instance on this box that I use for the repository and other small development I do. OEM works OK, discovers the instance, etc. Just to check a few things out, I went to a different NT workstation with client code on it, made an entry in tnsnames to access the first instance. I can't tnsping or access with sql*plus. I get a no listener available message. I can ping the box with the hostname.

Why can't I get to the instance? Is there a problem because this is NT workstation and not server? or a security problem? or maybe I need enable a user through user administration?

Thanks for any help... Received on Wed Aug 02 2000 - 00:00:00 CDT
