Hi Abhijit,
Could you follow the steps once you login to the server
my computer -> Right click 'manage'
Look for "Shared Folders"
Select " Shares" . This will list down all the folders which are shared.
Ensure that you have sapmnt and saploc entries under here. If not create them manually.
Select sapmnt -> right click 'Properties' . In security tab you need to add user "everyone" and provide full permission.
Post these steps check the results.
Hope this helps.
Regards,
Deepak Kori
