From another thread on the same issue:
If your computers are both behind a router, then you can try to enable Windows File Sharing in Firewall:
- Open McAfee SecurityCenter and go to Firewall feature, expand Ports and System Services;
- Look for "Windows File Sharing (NETBIOS).." and click on the checkbox before it;
Also make sure that the Firewall Permissions are "Full Access" and that the spooler sub system is included in the permissions.
Try that and see if it helps.
NetBios was checked, but spooler subsystem was 'block'ed. Thanks so much for the help.
