Anti-virus Exclusions

How do I stop the Anti-virus scanner from scanning all the servers on the local network? I’ve tried adding ‘\servername*’ to exclusion list, but it just carries on scanning. Have I missing something basic here?
I’ve searched the forum and found references to this but no solution.

Does this bring some extra insight to the table for youFile specification inc. using wildcards in CIS (Technical FAQ)?
