My company has an Oracle data source that I use to pull regular data from my operation. I had to re-start of my MS Servers and after restarting I cannot connect to this data source any longer. Prior to re-starting, I was able to connect. I can successfully connect to the same Oracle data source from two different machines.
When i try to connect, i get the error ORA-12541: No Listener. Everything I have found says that the listener needs to on the host server, i.e. the target oracle server one is pulling data from. Since I can successfully connect to that server from other computers but not my one server, that doesn't seem like it is the problem.
I can connect to other oracle data-sources from that server. Only this one connection seems to have been corrupted.
Any suggestions on how to trouble shoot?
