Tools - Copy File error

In EBS R12, after a concurrent request is run and the log file is viewed, Tools –> Copy File is selected, a browser window opens and displays the following message

An error occurred while attempting to establish an Applications File Server connection with the node FNDFS_NODE02. There may be a network configuration problem, or the TNS listener on node FNDFS_NODE02 may not be running. Please contact your system administrator.


Solution 1:
select distinct LOGFILE_NODE_NAME from FND_CONCURRENT_REQUESTS;

Also, check the tnsnames.ora for the correct entry of FNDSM_$TWO_TASK. If you have sqlnet.ora, ensure you have Admin server entry.
