I am trying to log in to SAPgui and getting an error:
Security Network Layer (SNC) error
This error message can indicate a number of things.
For the following circumstances
- Kerberos is already installed.
- The error persists even after getting a ticket directly in Kerberos.
The error can sometimes be resolved by deleting any old desktop shortcuts, and launching the application directly from Start>>Programs>>SAP Frontend>>Production.
If this works, the desktop shortcut can be re-created from the start menu entry.
If this does not resolve your situation, contact the Help Desk for further troubleshooting assistance.
