title: TNS no listener error connecting to remote oracle database through VPN
body: <p>I am using Windows 7 professional.  I have reloaded oracle client.  Up until two days ago I connected with no problem.  My company did a computer update and made a change in my VPN, but the help desk has been no help.  Team mate can connect with no issues with same tnsnames and sqlnet.  When trying to connect to the database via TOAD, Pl Sql Developer, Visual Stuido, or SSRS, I get TNS no listener error.  I have checked my TNSNames file.  The entry has not changed and is:  idwbcmip = 
   (DESCRIPTION = 
     (ADDRESS = (PROTOCOL = TCP)(HOST = 165.136.98.57)(PORT = 1521))
     (CONNECT_DATA = 
       (SERVER = DEDICATED)
       (SID = idwbcmip)
      )
    )</p>
  
  <p>I have checked Sqlnet.ora and it is: SQLNET.AUTHENTICATION_SERVICES= (NTS)</p>
  
  <p>NAMES.DIRECTORY_PATH=(TNSNAMES,LDAP, EZCONNECT)</p>
  
  <p>TNSAdmin is set to correct path</p>
  
  <p>I have tried to start a listener via lsnrctl and received a tns protocol adapter error.</p>
  
  <p>I have contacted the host of the database to check listener, but if team mate can access, it is obviously turned on.</p>
  
  <p>I have checked my services.  The only ones available are 
  Oracle MTSRecovery Service  Started
  OracleOraClient11g_home2CMAdmin won't start, can't find
  OracleOraClient11ghome2CMan  won't start, can't find
  OracleOraClient12Home1_34bitMTSRecoveryService won't start, can't find
  OracleOraDb11g_home1ClrAgent  Started
  OracltRemExecServiceV2 Started
  OraClient11g_home2_OracleSchedulerExecutionAgent won't start, can't find</p>
  
  <p>TNSPing gives tns no listener error</p>
  
  <p>Our company provided a tunnel through our firewall to client company firewall. </p>
  
  <p>At a loss on what else to check.  </p>
