Hi all,

I am facing "End of File of comm channel" after a connection with server is established, and below mentioned log is being generated in sqlnet.log file.It is worth mentioning that i am able to connect to the server fine .It is only after a minute or so ,when i run a query i get "END of File on comm channel" error.There are various other machines(in the same VLAN zone) where the client is connecting to the same server without any problem.

Fatal NI connect error 12560, connecting to:
(DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleORCL)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))(CON NECT_DATA=(SID=ORCL)(CID=(PROGRAM=c:\oracle\ora81\bin\sqlplus.exe)(HOST=MERAJWANI)(USER=meraj))))
