You will get a similar message in the probe test connecton or probe log:
sap_basis (12) login failed, Connector path is not correct, path does not contain sapjco3.dll and sapjco3.jar.
Confirm the variables as described in the probe documentation ie.:
CLASSPATH=D:\sapjco\sapjco3.jar
Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;D:\sapjco\
Java options:
-cp "./*;D:/sapjco/*"
Content of d:\sapjco:
Release : 9.x or later
Component : UIM - SAP_BASIS
2.02 or later requires additional files in the sapjco folder. It should contain
Correct sapjco folde so just download it from Sap Market place with the Sap Administrator help and then apply the probe.
Sap_basis 2.01 version should work as a workaround
