This plugin helps with publishing artifacts to net share.
You should have installed TeamCity, JAVA, ANT run ant in root directory get compiled TeamCityNetPublisherPlugin.zip from dist folder
Copy TeamCityNetPublisherPlugin.zip to plugins directory (for windows %USERPROFILE%.BuildServer\plugins) and resart TeamCity server
Add "Publish artifacts to specific path" build feature and specify path to publishing like this "\SERVER\SHARE\BUILDS%env.BUILD_NUMBER%'" or "C:\PATH\MY BUILDS%env.BUILD_NUMBER%" You can setup publishing for all builds or only for success. TemCity build server acount should have permissions to specified publishing path.
