when we try to get access in any shared folder from any server or from any pc then the problem like "You can’t access this shared folder because your organization’s security policies block unauthenticated guest access" and another few more. this is really irritating. we have shown you how to solve this problem. 
First Click on your "Windows button+R"
Then Type "regedit.msc" and click ok
Then choose "computer Properties"
Then Findout "Administrative Templetes"
there you will have so many options 
from those findout "Network"
Finally try to get "Lanman Workstation"
double click on it
Then you will have four options there then findout "Enable insecure guest logons" then double click on it
there you will get 3 options.
simply click on enabled and apply also ok.
on last stage search by the same IP or shared name. 
Hopefully you will have best solution.
