Issue/Introduction
When building the "SEE Client.msi" and "SEE Client_x64.msi" files from Symantec Endpoint Encryption Software Setup in Symantec Endpoint Encryption Manager, you may see an error that refers to The request failed with HTTP status 401: Unauthorized after you click on the Next button on the Management Agent Installation Settings - Communication page. All the fields on this page are pre-populated except for the Password and you see this error even though you enter the correct password:
Environment
Symantec Endpoint Encryption 11.3 and above.
Cause
Windows loopback detection has been triggered. Windows loopback detection is enabled by default in Windows.
Resolution
To disable loopback detection, please do the following.
First, check that loopback detection is enabled. Open a command prompt with local administrator rights and run this command. By default, the registry key should not be found:
C:\>reg query HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v DisableLoopbackCheck
ERROR: The system was unable to find the specified registry key or value.
To disable loopback detection, run this command to add the DisableLoopbackCheck key with a value of 1:
C:\>reg add HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v DisableLoopbackCheck /t REG_DWORD /d 1
The operation completed successfully.
To check the key has been added, run the reg query command again:
C:\>reg query HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v DisableLoopbackCheck
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
DisableLoopbackCheck REG_DWORD 0x1
After creating the "SEE Client.msi" and "SEE Client_x64.msi" files, you can delete the DisableLoopbackCheck key:
C:\>reg delete HKLM\SYSTEM\CurrentControlSet\Control\Lsa /v DisableLoopbackCheck /f
The operation completed successfully.
