Hi Lutz,
In our investigation we found that environmental variable SNC_LIB is set to gsskrb5.dll, temporarily we changed it to C:\Program Files (x86)\SAP\FrontEnd\SAPGUI\Encryption\secgss.dll
Now we can access our SRM system logon page with lock sign, which describes that we have SNC now over my connection.
But now apart from SRM system, we are not able to access the other systems through SAP GUI.
I believe this is due to the switchover from gsskrb5.dll to secgss.dll.
Could you please guide us on how can we keep environmental variable SNC_LIB as gsskrb5.dll and access all systems as well as SRM.
Regards,
