The  system error 126 indicates that a dependancy could not be found. Traditionally, the cause of this ODBC error is that the client software (SQL*NET) is not loaded

However,  this could also be a driver / sqlnet mismatch.   THe client software version can be higher than the database version (ie:  Using 8.1.6 Net8 client to connect to an Oracle 7.3.4 database)
The 8.x drivers will require a client of the matching version. This means that an 8.0.4 driver will expect to find an  8.0.4 client installation (including net 8) and the 8.1.x driver will expect to find an 8.1.x client install, etc.
Or with Oracle 7 client software including Oracle ODBC driver version 2.5.3.1.x

Did you use SMS to install?  
Sometimes, sms installs sets up the ODBC registry settings incorrectly,
Example:,
 hkey_local_machine\software\odbc\odbcinst.ini\Oracle73 Ver 2.5
the entries are set to point to c:\winnt\system32 instead of
 c:\orant\odbc250
or wherever your Oracle home resides.

Check this out,  bet it will solve the problem,
sincerely,
dBalaski

Thanks I will try and let you know.

Also use tnsping80 or tnsping.
Synatx is tnsping80 SIDNAME
or            tnsping  SIDNAME

by this you know whether you are able to contact Oracle SID ot nor. If it is working then you need to try for ODBC connections. I fthis is not working then you need to fix this problem first.

Thanks on the tip TNSPING.
PING host and TNSPING database are OK.
I am working with win2000 but i see that the dir c:\orawin95 is on my c-drive.
The sms admin is making available a joint oracle 8 & oracle 7 odbc script, as you suggested above.
Thank you for the professional help.
