I believe that your problem is that services run under Local
System account.  Normally Local System account would not have
a drive mapping Y:\.  You can change the account that a service
runs under in the Service Manager-Log On tab.  Normally you
wouldn't run services from mapped drives, they would be
installed on local machine and started from there.  If services
need to access mapped drives, you need to put full UNC
pathnames to access them or run the services under an account
that has the drives mapped properly.
