When running a migration task on a DFS target the following error may be returned:
"Error: E19: A valid server license could not be found on the target computer. Reason: ServerLicense:: CheckServerLicense-> The server License which was found for \\target_computer in not a valid license."
In this scenario the target of a Quest Storage Consolidator job was a DFS share.
The QSS license was deployed to a target via the DFS name and but the license was deployed to the admin share on the DC providing the DFS referral so the actual target File Server was not correctly licensed.
By default the licenses are put in the admin$ share on the target. Check for a QSMigLic.bin file in this share on the target server. If there is not one there search the entire hard drive. If you find any QSMigLic.bin files rename the file and deploy a license to the server again.
If the requirement is to simply migrate data into a DFS topology so that it gets replicated to other servers by DFS, then a target server could be specified by its UNC path rather than the DFS name then only that Target File Server would need to be licensed.
