PROBLEMWhen doing an interactive scan, GFI LanGuard is causing logon failures even though "Alternative Credentials" are used.
ENVIRONMENTGFI LanGuard - All versions
All supported platforms
1. Make sure the account generating the logon failures is not being used somewhere in the configuration for the scan:
2. Launch LanGuard.exe (User Interface) with a local administrative account - using the "Run as different user" option
3. Launch LanGuard.exe (User Interface) with another domain account that has administrative rights - using the "Run as different user" option.
4. Scan using a "scheduled scan"
See the following article for more details: Best practices: accounts, permissions and “alternative credentials”.
