Hi,
Double click on the job in "Job Setup". "Selections" > "View format" > "Text".
Search for the entry of the "Server" name select and delete the corresponding entry.
Run the job again.
The other workaround is to simply create a completely new job which obviously wont have the old server name!
Hope this helps.
