Re: Need help with a net 8 problem "ORA-12638: Credential retrieval failed"

Hi Chris,

Do you normally log in using a username/password or is your account set up to use native server authentication?
If it's the latter, you'll need to get it changed to standard password authentication as Win95 does not support native server authentication.

Next, check you SQLNET.ORA (lives with the TNSNAMES.ORA file). There should be a line that reads: SQLNET.AUTHENTICATION_SERVICES=(NONE) Change it if it's set to SQLNET.AUTHENTICATION_SERVICES=(NTS). - NTS is for Native authentication.

Hope this helps,
Kevin
