When you are trying to deploy SCU via LIveUpdate to the CCS Manager in remote domain you are getting this error message - "Install User logon failed. The user name or password is incorrect".
Additionally you are able to login to target CCS Manager using same credential and user has admin rights as well.
"Install User logon failed. The user name or password is incorrect".
Provided the CCS install user is not trusted to other domain.
1. Please setup domain trust between affected domain's.
2. Provide the CCS install user which is trusted to other domain.
3. run the CCS infra or content installer in Silent mode on remote server - you can use psexec for this on remote server.
e.g. psexec \\remote-pc -u “DOMAIN\Administrator” -p “password” cmd /c “\\server\share\CCS_12_0_2018-2_SCU_Win.exe /quiet”
Info: You can use psexec for this on remote server. More information about silent mode you will find in CCS_12_5_Upgrade_Guide.pdf - please see attachment.
