Replication Access denied in Replication
I had the same problem and solved with the following steps:


Right click shared folder and click properties
Go to Advanced Sharing > Permissions
In dialog "permissions for "
Add snapshot user (\repl_snapshot in my case)
Grant "Full Control" 
All should be ok now, and to verify
Go to "View Snapshot Agent status" and click start, you should now see something like "[100%] A snapshot of 1 article(s) was generated."
