This guide outlines what to do when you experience the following STAS related errors:
- Failed: Can not start service.: STAS
- Fatal Error: The data area passed to a system call is too small
- Fatal Error: The service did not start due to a logon failure
The most likely cause of these issues are related to the credentials provided during STAS installation.
The user accounts used to install STAS should meet the following requirements:
- User must have the "Right to logon as a service" (even if Administrator)
- User must be able to monitor the Security event log
- User should be part of the Backup Operations and Event Log Readers group
- Full NTFS permission to the STAS folder
After confirming these requirements. On Windows, navigate to:
- Start > Run
- Type services.msc
- Find the Sophos Transparent Authentication Service
-
- Right-click Logon and enter the STAS user
- Click Apply
- Go back to STAS and the service should be started already
