You can do a local install on the remote machine by following the doc:
http://seer.entsupport.symantec.com/docs/265736.htm
Or you can check the following for push install:
1) Credentials should be proper. Make sure in the Domain field, you are entering the Remote machine's name if the machine is not in a domain.
2) Try a local admin account, if using a domain admin account.
3) Check whether you can ping by IP, name and also connect using the UNC path (
\\<Remote Server>\C$ )
