Monitoring network folder

I am very new to Mac and Hazel. I am monitoring a folder on my network and is working fine. The problem I ran into was I took my MacBook to work and when I came home I checked to see why Hazel was not processing my folder and saw this:
Scan folder is not accessible. Exiting.
2014-02-05 19:59:41.424 HazelHelper[214] Worker process for folder /Volumes/Documents/Scans did not check in.
When I browsed to the folder manually then Hazel starting working again. I know why it is happening but just don't know what to do
I guess my question is how should I handle that. I was hoping it would just start working again once I was home.
Thanks for any help you can give.
