Deployment fails with Error 1326: Logon failure: unknown user name or bad password.
The credentials for the target machine are correct but deployment is failing.
This happens when you have your patch repository set to a UNC path on a network share. During the deployment Protect will use the target machines assigned credentials to authenticate to the share to copy the patches to the target machine but those credentials are not valid for the share.
Move the patch repository back to a local drive on the Protect Console or add the needed permissions to the share.
