If the Rolling Restart log is giving an error 4 when trying to connect to a multiple remote servers, and the error.txt file has the entry 'WMI GSUC error 4', be sure that WMI is accessible from the console to the remote RR client computer and is not being blocked by any firewalls.
If the error is occurring on just one computer, run a re-registering batch file on the remote computer to re-register WMI. At an Administrator Command Prompt on the remote computerput these into a batch file and run it:
for /f %s in ('dir /b /s *.dll') do regsvr32 /s %s net stop /y winmgmt for /f %s in ('dir /b *.mof *.mfl') do mofcomp %s net start winmgmt
